CLONING
Gearing et al. (1991) isolated a cDNA clone encoding the human LIF
read morereceptor by expression screening of a human placenta cDNA library. The
LIFR gene encodes a 1,097-amino acid transmembrane protein that is
composed of 6 different domains: 2 cytokine receptor homology domains
(CRH1 and CRH2), 1 immunoglobulin-like domain, 1 type III fibronectin
domain with 3 modules, 1 transmembrane domain, and 1 cytoplasmic domain.
GENE STRUCTURE
The LIFR gene contains 20 exons (Tomida and Gotoh, 1996).
GENE FUNCTION
The LIF receptor (LIFR) is the low-affinity binding chain that, together
with the high-affinity converter subunit gp130 (600694), forms a
high-affinity receptor complex that mediates the action of the
leukemia-inhibitory factor (LIF; 159540). LIF is a polyfunctional
cytokine that affects the differentiation, survival, and proliferation
of a wide variety of cells in the adult and the embryo (Gearing et al.,
1993). The high-affinity complex also binds a related cytokine,
oncostatin M (OSM; 165095). Both LIFR and gp130 are members of a family
of cytokine receptors that includes components of the receptors for the
majority of hematopoietic cytokines and for cytokines that affect other
systems, including the ciliary neurotrophic factor (CNTF; 118945),
growth hormone (GH; 139250), and prolactin (PRL; 176760).
Bozec et al. (2008) demonstrated that the FOS-related protein FRA2
(601575) controls osteoclast survival and size. They observed that bones
of Fra2-deficient newborn mice had giant osteoclasts, and signaling
through LIF and its receptor LIFR was impaired. Similarly, newborn
animals lacking Lif had giant osteoclasts, and Bozec et al. (2008)
demonstrated that LIF is a direct transcriptional target of FRA2 and
c-JUN (604641). Moreover, bones deficient in Fra2 and Lif were hypoxic
and expressed increased levels of hypoxia-induced factor 1-alpha (HIF1A;
603348) and Bcl2 (151430). Overexpression of Bcl2 was sufficient to
induce giant osteoclasts in vivo, whereas Fra2 and Lif affected Hif1a
through transcriptional modulation of the Hif prolyl hydroxylase Phd2
(606425). This pathway is operative in the placenta, because specific
inactivation of Fra2 in the embryo alone did not cause hypoxia or the
giant osteoclast phenotype. Bozec et al. (2008) concluded that thus,
placenta-induced hypoxia during embryogenesis leads to the formation of
giant osteoclasts in young pups.
MAPPING
Using somatic cell hybrid analysis, Gearing et al. (1993) demonstrated
that the human LIFR gene is located on 5p13-p12. By interspecific
backcross analysis, they showed that the murine locus is on chromosome
15 in a region of homology with human chromosome 5p. In both human and
mouse genomes, the LIFR locus was linked to the genes encoding the
receptors for interleukin-7 (IL7R; 146661), prolactin (PRLR; 176761),
and growth hormone (GHR; 600946).
MOLECULAR GENETICS
Stuve-Wiedemann syndrome (STWS; 601559) is a severe autosomal recessive
disorder characterized by bowing of the long bones, with cortical
thickening, flared metaphyses with coarsened trabecular pattern,
camptodactyly, respiratory distress, feeding difficulties, and
hyperthermic episodes responsible for early lethality. Clinical overlap
with Schwartz-Jampel type 2 syndrome (SJS2) suggested that STWS and SJS2
could be allelic disorders; see 601559. Through studying a series of 19
families with STWS/SJS2, Dagoneau et al. (2004) mapped the disease gene
to 5p13.1 at locus D5S418 and identified 14 distinct null mutations in
the 19 families. An identical frameshift insertion (653_654insT;
151443.0001) was identified in families from the United Arab Emirates,
suggesting founder effect. Twelve of the 14 mutations predicted
premature termination of translation. Functional studies indicated that
these mutations altered the stability of LIFR mRNA transcripts,
resulting in the absence of the LIFR protein and the impairment of the
JAK/STAT3 signaling pathway in patient cells. The authors concluded that
STWS and SJS2 are indeed a single clinically and genetically homogeneous
condition due to null mutations in the LIFR gene. Dagoneau et al. (2004)
had considered LIFR to be a good candidate gene because, in addition to
its map location, Lifr -/- mice present with reduction of fetal bone
volume, with an increased volume of osteoclasts, reduction of astrocyte
numbers in spinal cord and brain, and perinatal death (Ware et al.,
1995).

LIFR, 1-BP INS, 653T
In 5 Omani and Yemeni families originating from the United Arab
Emirates, all with consanguineous parents, Dagoneau et al. (2004) found
that children with Stuve-Wiedemann/Schwartz-Jampel type 2 syndrome
(601559) had a 1-bp insertion, 653_654insT, in exon 6 of the LIFR gene

LIFR, ARG597TER
In a family from Portugal, in 2 Gypsy families, and in 1 French family,
Dagoneau et al. (2004) found that the STWS/SJS2 syndrome (601559) was
associated with homozygosity for an arg597-to-stop (R597X) mutation in
exon 13 of the LIFR gene. This same mutation was found in compound
heterozygous state in 2 affected members of a Swiss family, the other
mutation being a 1-bp insertion, 2011_2012insT (151443.0003), which
resulted in frameshift and a stop 12 codons downstream.

In a girl with Stuve-Wiedemann syndrome (601559), born of consanguineous
Portuguese Gypsy parents, Gaspar et al. (2008) identified a homozygous
4-bp deletion (167delTAAC) in exon 3 of the LIFR gene, resulting in a
frameshift and premature termination. The child was alive at age 12
years and showed typical signs of the disorder, including bowed limbs,
facial dysmorphism, and later-onset dysautonomia. Gaspar et al. (2008)
noted that survival past infancy is unusual in this disorder.

mouse genomes, the LIFR locus was linked to the genes encoding the
receptors for interleukin-7 (IL7R; 146661), prolactin (PRLR; 176761),
and growth hormone (GHR; 600946).
MOLECULAR GENETICS
Stuve-Wiedemann syndrome (STWS; 601559) is a severe autosomal recessive
disorder characterized by bowing of the long bones, with cortical
thickening, flared metaphyses with coarsened trabecular pattern,
camptodactyly, respiratory distress, feeding difficulties, and
hyperthermic episodes responsible for early lethality. Clinical overlap
with Schwartz-Jampel type 2 syndrome (SJS2) suggested that STWS and SJS2
could be allelic disorders; see 601559. Through studying a series of 19
families with STWS/SJS2, Dagoneau et al. (2004) mapped the disease gene
to 5p13.1 at locus D5S418 and identified 14 distinct null mutations in
the 19 families. An identical frameshift insertion (653_654insT;
151443.0001) was identified in families from the United Arab Emirates,
suggesting founder effect. Twelve of the 14 mutations predicted
premature termination of translation. Functional studies indicated that
these mutations altered the stability of LIFR mRNA transcripts,
resulting in the absence of the LIFR protein and the impairment of the
JAK/STAT3 signaling pathway in patient cells. The authors concluded that
STWS and SJS2 are indeed a single clinically and genetically homogeneous
condition due to null mutations in the LIFR gene. Dagoneau et al. (2004)
had considered LIFR to be a good candidate gene because, in addition to
its map location, Lifr -/- mice present with reduction of fetal bone
volume, with an increased volume of osteoclasts, reduction of astrocyte
numbers in spinal cord and brain, and perinatal death (Ware et al.,
1995).

In 5 Omani and Yemeni families originating from the United Arab
Emirates, all with consanguineous parents, Dagoneau et al. (2004) found
that children with Stuve-Wiedemann/Schwartz-Jampel type 2 syndrome

In a family from Portugal, in 2 Gypsy families, and in 1 French family,
Dagoneau et al. (2004) found that the STWS/SJS2 syndrome (601559) was
associated with homozygosity for an arg597-to-stop (R597X) mutation in
exon 13 of the LIFR gene. This same mutation was found in compound
heterozygous state in 2 affected members of a Swiss family, the other
mutation being a 1-bp insertion, 2011_2012insT (151443.0003), which
resulted in frameshift and a stop 12 codons downstream.

In a girl with Stuve-Wiedemann syndrome (601559), born of consanguineous
Portuguese Gypsy parents, Gaspar et al. (2008) identified a homozygous
4-bp deletion (167delTAAC) in exon 3 of the LIFR gene, resulting in a
frameshift and premature termination. The child was alive at age 12
years and showed typical signs of the disorder, including bowed limbs,
facial dysmorphism, and later-onset dysautonomia. Gaspar et al. (2008)
noted that survival past infancy is unusual in this disorder.

*FIELD* TX
A number sign (#) is used with this entry because of evidence that
Stuve-Wiedemann syndrome (STWS), also known as neonatal Schwartz-Jampel
syndrome type 2 (SJS2), is caused by mutation in the leukemia inhibitory
factor receptor gene (LIFR; 151443) on chromosome 5p13.
DESCRIPTION
Stuve-Wiedemann syndrome (STWS) is an autosomal recessive disorder
characterized by bowing of the long bones and other skeletal anomalies,
episodic hyperthermia, and respiratory and feeding distress usually
resulting in early death (Dagoneau et al., 2004).
See also 'classic' Schwartz-Jampel syndrome type 1 (SJS1; 255800), a
phenotypically similar but genetically distinct disorder caused by
mutation in the HSPG2 gene (142461) on chromosome 1p36.1-p34.
CLINICAL FEATURES
Stuve and Wiedemann (1971) reported 2 sisters and a first-cousin male
with congenital bowing of the long bones. Other features included short
stature, camptodactyly with ulnar deviation, and contractures of the
elbows and fingers. Radiographically, the long bones were short and
thick with large metaphyses. Although the clavicles were normal, there
was a broad coracoid process bilaterally, long scapulae, and relatively
thin ribs. The pubic and ischial bones were broad and the ilia
relatively small. One patient died after 10 days of life from
respiratory insufficiency with apnea; her sister developed hyperthermia
with temperatures as high as 41 degrees centigrade and died on day 5 of
life. The male first cousin to these 2 girls had identical congenital
flexion contractures of the fingers and toes and died of respiratory
insufficiency as a neonate. The parents of the 2 sibships were related;
the mothers were sisters and the fathers were brothers. Stuve and
Wiedemann (1971) postulated that the disorder in this family represented
a specific condition.
Farrell et al. (1987) described a newborn male with severe
manifestations resulting in death at 12 days of age.
Kozlowski and Tenconi (1996) reported a 3-year-old boy with
Stuve-Wiedemann syndrome. At age 30 months, he had short limbs with an
increased upper to lower segment ratio, bowing of the femora, tibiae,
and radii, with decreased extension at the knees and elbows. He had
short fingers with flexion of all the small joints in the hand and
adduction of the thumb, as well as camptodactyly of the second through
fourth fingers. Talipes valgus was observed. On radiographic
examination, bowing of the long bones of the lower limbs and forearms
was documented; wide metaphyses with decreased density and abnormal
trabecular pattern were also seen. Kozlowski and Tenconi (1996)
discussed the differential diagnosis of Stuve-Wiedemann syndrome,
campomelic dysplasia (114290), and kyphomelic dysplasia (211350).
Al-Gazali (1993) and Al-Gazali et al. (1996) reported 11 children in 5
families from the United Arab Emirates with what they termed 'severe
neonatal Schwartz-Jampel syndrome type 2.' All presented at birth with
skeletal abnormalities and feeding difficulties. Five had the typical
pursed appearance of the mouth. Nine died from respiratory
complications: 5 in the neonatal period and 4 before 2 years of age. The
patients were mostly of Omani origin. Only 7 of 17 previously reported
neonatal SJS cases had a similar severe course, suggesting to Al-Gazali
et al. (1996) that there is a subgroup of SJS with severe respiratory
and feeding problems, poor prognosis, and early death.
Chabrol et al. (1997) reported 3 newborn boys from 2 consanguineous
Gypsy families with manifestations of Stuve-Wiedemann syndrome. The 2
families were presumably unrelated. Two of the infants died shortly
after birth, whereas the third was alive at the age of 1 year. Besides
hyperthermic episodes, 1 patient had hyperaminoaciduria, hepatic
failure, and megaloblastic anemia, which prompted investigation of the
mitochondrial respiratory chain in 2 cases. Abnormal results consisting
of decreased activities of complexes I and IV were found in both
patients. The finding of the Stuve-Wiedemann phenotype and abnormal
mitochondrial metabolism from each of 2 infants from different families
supported a pathogenetic relationship between the 2. Radiographs of the
bony angulations were displayed.
Giedion et al. (1997) reported 2 sibs with neonatal SJS. One of them
showed short, bowed femora and fetal hypokinesia on ultrasound at 17
weeks' gestation. Both were severely affected with mask-like facies,
myopia, and multiple skeletal anomalies. One died at age 3 months,
whereas the other was alive at age 9 years with normal intelligence, but
was severely physically handicapped. Linkage was excluded from the SJS1
locus on chromosome 1p.
Cormier-Daire et al. (1998) reported findings in 8 patients with STWS
suggesting that the syndrome is clinically homogeneous. All patients had
feeding and swallowing difficulties, respiratory insufficiency, abnormal
appearance, muscle hypotonia, and postnatal short stature. Recurrent
episodes of unexplained fever occurred in all and were the cause of
death in 6 of the 8 patients. Parental consanguinity and sib recurrence
suggested autosomal recessive inheritance.
Cormier-Daire et al. (1998) suggested that STWS and neonatal
Schwartz-Jampel syndrome, or SJS type 2, were the same entity based on
similar clinical, radiologic, and histologic features. Superti-Furga et
al. (1998) also concluded that Schwartz-Jampel syndrome type 2 and
Stuve-Wiedemann syndrome should be considered the same entity. To test
for possible nosologic identity between these disorders, they reviewed
the literature and obtained a follow-up of the only 2 surviving
patients, one with SJS type 2 at age 10 years and another with STWS at
age 7 years. Patients reported as having either neonatal SJS or STWS
presented a combination of a severe, prenatal-onset neuromuscular
disorder with congenital joint contractures, respiratory and feeding
difficulties, tendency to hyperthermia, and frequent death in infancy
and a distinct campomelic-metaphyseal skeletal dysplasia. The follow-up
observation of an identical and unique pattern of progressive bone
dysplasia in the 2 patients (one with SJS type 2, one with STWS)
surviving beyond infancy added to the evidence in favor of identity.
Raas-Rothschild et al. (2003) reported 2 sibs with Stuve-Wiedemann
syndrome who died of respiratory failure due to pulmonary hypertension.
The parents were first-cousin Muslim Arabs originating from the
Jerusalem area. Echocardiographic and postmortem analysis showed that
both patients had a closed ductus arteriosus, dilated pulmonary arteries
with extremely hypertrophied walls, and right-to-left shunting through a
patent foramen ovale. The authors postulated a mechanism in which
antenatal premature closure of the ductus arteriosus could result in
increased right ventricular afterload and increased pulmonary artery
pressure, ultimately causing pulmonary artery hypertrophy and
hypertension. Raas-Rothschild et al. (2003) suggested that some patients
with Stuve-Wiedemann syndrome and early neonatal death due to
respiratory failure may have had pulmonary hypertension.
- Patients with Longer Survival
Stuve-Wiedemann syndrome is typically lethal in the neonatal period.
Chen et al. (2001), who described the case of a child surviving to age 9
years, stated that only 2 patients with long survival had been reported.
In addition to characteristic features of STWS, their patient had a
number of unique clinical signs, including lack of corneal and patellar
reflexes, smooth tongue with no fungiform papillae, chronic gingival
abscesses, mottled and otherwise poor dentition, blotchy pigmentation of
the skin, unusual infections, multiple fractures, and progressive
scoliosis. Cytogenetic analysis identified mosaicism for a supernumerary
marker chromosome, seen in the majority of amniocytes, blood cells, and
skin fibroblasts. The marker chromosome was shown to be derived from
chromosome 5 and to contain euchromatin.
Al-Gazali et al. (2003) reported 3 children from 2 inbred Arab families
with Stuve-Wiedemann syndrome who had survived the first year of life;
their ages were 6, 2.8, and 2 years. All exhibited a characteristic
phenotype resembling that described by Chen et al. (2001). In all 3
children, the skeletal abnormalities progressed to severe bowing of the
long bones with prominent joints and severe spinal deformity. All
exhibited neurologic symptoms including temperature instability with
excessive sweating, reduced pain sensation with repeated injury to the
tongue and limbs, absent corneal reflexes, and a smooth tongue. All 3
children had normal intelligence. Radiologic changes included
undertubulation of the diaphyses, rarefaction and striation of
metaphyses, destruction of the femoral heads, and spinal deformity. This
report confirmed that survival in this syndrome is possible and that the
prognosis improves after the first year of life. It also supported the
existence of a characteristic phenotype in Stuve-Wiedemann syndrome
survivors that includes neurologic symptoms reminiscent of dysautonomia
in addition to the skeletal abnormalities and distinctive radiologic
features.
Gaspar et al. (2008) reported long-term follow-up of a 12-year-old girl,
born of consanguineous Portuguese Gypsy parents, with STWS confirmed by
genetic analysis (151443.0004). Early in infancy she had hypotonia,
facial myotonia, low-set ears, a short neck, short bowed limbs,
contractures of the elbows and knees, camptodactyly, and talipes
equinovarus. She was a poor feeder and had recurrent bouts of fever and
recurrent respiratory problems. In the ensuing years, she developed
severe corneal opacities, progressive scoliosis, more prominent joint
contractures, and ulnar deviation of the hands. Autonomic instability
included poor body temperature regulation, with asymmetric and
paradoxical sweating, and areas of hypoperfusion and hyperperfusion of
the trunk and extremities. Her cognitive development was excellent.
Other features included absent corneal reflexes, smooth tongue, and poor
dentition with chronic dental abscesses. She lost her ability to walk
and became wheelchair dependent at age 9. In a review of the few STWS
patients with long survival, Gaspar et al. (2008) concluded that the
major symptoms influencing daily life in these patients are loss of
vision, paradoxical sweating/shivering, severe spinal deformity,
spontaneous fractures, and limited mobility.
INHERITANCE
Wiedemann and Stuve (1996) gave an update and a historical footnote, and
noted that reported cases were consistent with autosomal recessive
inheritance.
MAPPING
Giedion et al. (1997) and Brown et al. (1997) demonstrated that neonatal
Schwartz-Jampel syndrome type 2 was not linked to chromosome 1p36.1-p34,
where 'classic' Schwartz-Jampel syndrome maps.
Through a study of a series of 19 patients with STWS/SJS2, Dagoneau et
al. (2004) mapped the disease gene to chromosome 5p13.1 at marker
D5S418.
MOLECULAR GENETICS
In patients with Stuve-Wiedemann syndrome, Dagoneau et al. (2004)
identified mutations in the leukemia inhibitory factor receptor gene
(LIFR; see, e.g., 151443.0001-151443.0003). Some of the patients had
been reported earlier by Al-Gazali et al. (1996, 2003), Chabrol et al.
(1997), Cormier-Daire et al. (1998), and Superti-Furga et al. (1998).
NOMENCLATURE
Chabrol et al. (1997) used the abbreviation SWS for this disorder, but
this abbreviation had already been used for Sturge-Weber syndrome
(185300).

*FIELD* TX
A number sign (#) is used with this entry because of evidence that
Stuve-Wiedemann syndrome (STWS), also known as neonatal Schwartz-Jampel
syndrome type 2 (SJS2), is caused by mutation in the leukemia inhibitory
factor receptor gene (LIFR; 151443) on chromosome 5p13.
DESCRIPTION
Stuve-Wiedemann syndrome (STWS) is an autosomal recessive disorder
characterized by bowing of the long bones and other skeletal anomalies,
episodic hyperthermia, and respiratory and feeding distress usually
resulting in early death (Dagoneau et al., 2004).
See also 'classic' Schwartz-Jampel syndrome type 1 (SJS1; 255800), a
phenotypically similar but genetically distinct disorder caused by
mutation in the HSPG2 gene (142461) on chromosome 1p36.1-p34.
CLINICAL FEATURES
Stuve and Wiedemann (1971) reported 2 sisters and a first-cousin male
with congenital bowing of the long bones. Other features included short
stature, camptodactyly with ulnar deviation, and contractures of the
elbows and fingers. Radiographically, the long bones were short and
thick with large metaphyses. Although the clavicles were normal, there
was a broad coracoid process bilaterally, long scapulae, and relatively
thin ribs. The pubic and ischial bones were broad and the ilia
relatively small. One patient died after 10 days of life from
respiratory insufficiency with apnea; her sister developed hyperthermia
with temperatures as high as 41 degrees centigrade and died on day 5 of
life. The male first cousin to these 2 girls had identical congenital
flexion contractures of the fingers and toes and died of respiratory
insufficiency as a neonate. The parents of the 2 sibships were related;
the mothers were sisters and the fathers were brothers. Stuve and
Wiedemann (1971) postulated that the disorder in this family represented
a specific condition.
Farrell et al. (1987) described a newborn male with severe
manifestations resulting in death at 12 days of age.
Kozlowski and Tenconi (1996) reported a 3-year-old boy with
Stuve-Wiedemann syndrome. At age 30 months, he had short limbs with an
increased upper to lower segment ratio, bowing of the femora, tibiae,
and radii, with decreased extension at the knees and elbows. He had
short fingers with flexion of all the small joints in the hand and
adduction of the thumb, as well as camptodactyly of the second through
fourth fingers. Talipes valgus was observed. On radiographic
examination, bowing of the long bones of the lower limbs and forearms
was documented; wide metaphyses with decreased density and abnormal
trabecular pattern were also seen. Kozlowski and Tenconi (1996)
discussed the differential diagnosis of Stuve-Wiedemann syndrome,
campomelic dysplasia (114290), and kyphomelic dysplasia (211350).
Al-Gazali (1993) and Al-Gazali et al. (1996) reported 11 children in 5
families from the United Arab Emirates with what they termed 'severe
neonatal Schwartz-Jampel syndrome type 2.' All presented at birth with
skeletal abnormalities and feeding difficulties. Five had the typical
pursed appearance of the mouth. Nine died from respiratory
complications: 5 in the neonatal period and 4 before 2 years of age. The
patients were mostly of Omani origin. Only 7 of 17 previously reported
neonatal SJS cases had a similar severe course, suggesting to Al-Gazali
et al. (1996) that there is a subgroup of SJS with severe respiratory
and feeding problems, poor prognosis, and early death.
Chabrol et al. (1997) reported 3 newborn boys from 2 consanguineous
Gypsy families with manifestations of Stuve-Wiedemann syndrome. The 2
families were presumably unrelated. Two of the infants died shortly
after birth, whereas the third was alive at the age of 1 year. Besides
hyperthermic episodes, 1 patient had hyperaminoaciduria, hepatic
failure, and megaloblastic anemia, which prompted investigation of the
mitochondrial respiratory chain in 2 cases. Abnormal results consisting
of decreased activities of complexes I and IV were found in both
patients. The finding of the Stuve-Wiedemann phenotype and abnormal
mitochondrial metabolism from each of 2 infants from different families
supported a pathogenetic relationship between the 2. Radiographs of the
bony angulations were displayed.
Giedion et al. (1997) reported 2 sibs with neonatal SJS. One of them
showed short, bowed femora and fetal hypokinesia on ultrasound at 17
weeks' gestation. Both were severely affected with mask-like facies,
myopia, and multiple skeletal anomalies. One died at age 3 months,
whereas the other was alive at age 9 years with normal intelligence, but
was severely physically handicapped. Linkage was excluded from the SJS1
locus on chromosome 1p.
Cormier-Daire et al. (1998) reported findings in 8 patients with STWS
suggesting that the syndrome is clinically homogeneous. All patients had
feeding and swallowing difficulties, respiratory insufficiency, abnormal
appearance, muscle hypotonia, and postnatal short stature. Recurrent
episodes of unexplained fever occurred in all and were the cause of
death in 6 of the 8 patients. Parental consanguinity and sib recurrence
suggested autosomal recessive inheritance.
Cormier-Daire et al. (1998) suggested that STWS and neonatal
Schwartz-Jampel syndrome, or SJS type 2, were the same entity based on
similar clinical, radiologic, and histologic features. Superti-Furga et
al. (1998) also concluded that Schwartz-Jampel syndrome type 2 and
Stuve-Wiedemann syndrome should be considered the same entity. To test
for possible nosologic identity between these disorders, they reviewed
the literature and obtained a follow-up of the only 2 surviving
patients, one with SJS type 2 at age 10 years and another with STWS at
age 7 years. Patients reported as having either neonatal SJS or STWS
presented a combination of a severe, prenatal-onset neuromuscular
disorder with congenital joint contractures, respiratory and feeding
difficulties, tendency to hyperthermia, and frequent death in infancy
and a distinct campomelic-metaphyseal skeletal dysplasia. The follow-up
observation of an identical and unique pattern of progressive bone
dysplasia in the 2 patients (one with SJS type 2, one with STWS)
surviving beyond infancy added to the evidence in favor of identity.
Raas-Rothschild et al. (2003) reported 2 sibs with Stuve-Wiedemann
syndrome who died of respiratory failure due to pulmonary hypertension.
The parents were first-cousin Muslim Arabs originating from the
Jerusalem area. Echocardiographic and postmortem analysis showed that
both patients had a closed ductus arteriosus, dilated pulmonary arteries
with extremely hypertrophied walls, and right-to-left shunting through a
patent foramen ovale. The authors postulated a mechanism in which
antenatal premature closure of the ductus arteriosus could result in
increased right ventricular afterload and increased pulmonary artery
pressure, ultimately causing pulmonary artery hypertrophy and
hypertension. Raas-Rothschild et al. (2003) suggested that some patients
with Stuve-Wiedemann syndrome and early neonatal death due to
respiratory failure may have had pulmonary hypertension.
- Patients with Longer Survival
Stuve-Wiedemann syndrome is typically lethal in the neonatal period.
Chen et al. (2001), who described the case of a child surviving to age 9
years, stated that only 2 patients with long survival had been reported.
In addition to characteristic features of STWS, their patient had a
number of unique clinical signs, including lack of corneal and patellar
reflexes, smooth tongue with no fungiform papillae, chronic gingival
abscesses, mottled and otherwise poor dentition, blotchy pigmentation of
the skin, unusual infections, multiple fractures, and progressive
scoliosis. Cytogenetic analysis identified mosaicism for a supernumerary
marker chromosome, seen in the majority of amniocytes, blood cells, and
skin fibroblasts. The marker chromosome was shown to be derived from
chromosome 5 and to contain euchromatin.
Al-Gazali et al. (2003) reported 3 children from 2 inbred Arab families
with Stuve-Wiedemann syndrome who had survived the first year of life;
their ages were 6, 2.8, and 2 years. All exhibited a characteristic
phenotype resembling that described by Chen et al. (2001). In all 3
children, the skeletal abnormalities progressed to severe bowing of the
long bones with prominent joints and severe spinal deformity. All
exhibited neurologic symptoms including temperature instability with
excessive sweating, reduced pain sensation with repeated injury to the
tongue and limbs, absent corneal reflexes, and a smooth tongue. All 3
children had normal intelligence. Radiologic changes included
undertubulation of the diaphyses, rarefaction and striation of
metaphyses, destruction of the femoral heads, and spinal deformity. This
report confirmed that survival in this syndrome is possible and that the
prognosis improves after the first year of life. It also supported the
existence of a characteristic phenotype in Stuve-Wiedemann syndrome
survivors that includes neurologic symptoms reminiscent of dysautonomia
in addition to the skeletal abnormalities and distinctive radiologic
features.
Gaspar et al. (2008) reported long-term follow-up of a 12-year-old girl,
born of consanguineous Portuguese Gypsy parents, with STWS confirmed by
genetic analysis (151443.0004). Early in infancy she had hypotonia,
facial myotonia, low-set ears, a short neck, short bowed limbs,
contractures of the elbows and knees, camptodactyly, and talipes
equinovarus. She was a poor feeder and had recurrent bouts of fever and
recurrent respiratory problems. In the ensuing years, she developed
severe corneal opacities, progressive scoliosis, more prominent joint
contractures, and ulnar deviation of the hands. Autonomic instability
included poor body temperature regulation, with asymmetric and
paradoxical sweating, and areas of hypoperfusion and hyperperfusion of
the trunk and extremities. Her cognitive development was excellent.
Other features included absent corneal reflexes, smooth tongue, and poor
dentition with chronic dental abscesses. She lost her ability to walk
and became wheelchair dependent at age 9. In a review of the few STWS
patients with long survival, Gaspar et al. (2008) concluded that the
major symptoms influencing daily life in these patients are loss of
vision, paradoxical sweating/shivering, severe spinal deformity,
spontaneous fractures, and limited mobility.
INHERITANCE
Wiedemann and Stuve (1996) gave an update and a historical footnote, and
noted that reported cases were consistent with autosomal recessive
inheritance.
MAPPING
Giedion et al. (1997) and Brown et al. (1997) demonstrated that neonatal
Schwartz-Jampel syndrome type 2 was not linked to chromosome 1p36.1-p34,
where 'classic' Schwartz-Jampel syndrome maps.
Through a study of a series of 19 patients with STWS/SJS2, Dagoneau et
al. (2004) mapped the disease gene to chromosome 5p13.1 at marker
D5S418.
MOLECULAR GENETICS
In patients with Stuve-Wiedemann syndrome, Dagoneau et al. (2004)
identified mutations in the leukemia inhibitory factor receptor gene
(LIFR; see, e.g., 151443.0001-151443.0003). Some of the patients had
been reported earlier by Al-Gazali et al. (1996, 2003), Chabrol et al.
(1997), Cormier-Daire et al. (1998), and Superti-Furga et al. (1998).
NOMENCLATURE
Chabrol et al. (1997) used the abbreviation SWS for this disorder, but
this abbreviation had already been used for Sturge-Weber syndrome
(185300).
