CC -!- FUNCTION: Plays important roles in controlling the metabolism of
CC fatty acids at differents levels. Acts as a magnesium-dependent
CC phosphatidate phosphatase enzyme which catalyzes the conversion of
CC phosphatidic acid to diacylglycerol during triglyceride,
CC phosphatidylcholine and phosphatidylethanolamine biosynthesis in
CC the reticulum endoplasmic membrane. Acts also as a nuclear
CC transcriptional coactivator for PPARGC1A to modulate lipid
CC metabolism (By similarity).
CC -!- CATALYTIC ACTIVITY: A 1,2-diacylglycerol 3-phosphate + H(2)O = a
CC 1,2-diacyl-sn-glycerol + phosphate.
CC -!- COFACTOR: Mg(2+) (By similarity).
CC -!- ENZYME REGULATION: Inhibited by N-ethylmaleimide (By similarity).
CC -!- SUBCELLULAR LOCATION: Nucleus (By similarity). Cytoplasm, cytosol
CC (By similarity). Endoplasmic reticulum membrane (By similarity).
CC Note=Translocates to endoplasmic reticulum membrane with
CC increasing levels of oleate (By similarity).
CC -!- TISSUE SPECIFICITY: Expressed in liver, lung, kidney, placenta,
CC spleen, thymus, lymph node, prostate, testes, small intestine, and
CC colon.
CC -!- DOMAIN: Contains 1 Asp-Xaa-Asp-Xaa-Thr (DXDXT) motif, a catalytic
CC motif known to be essential for phosphatidate phosphatase activity
CC (By similarity).
CC -!- DOMAIN: Contains one Leu-Xaa-Xaa-Ile-Leu (LXXIL) motif, a motif
CC known to be a transcriptional binding motif (By similarity).
CC -!- DISEASE: Majeed syndrome (MAJEEDS) [MIM:609628]: An autosomal
CC recessive syndrome characterized by chronic recurrent multifocal
CC osteomyelitis that is of early onset with a lifelong course,
CC congenital dyserythropoietic anemia that presents as hypochromic,
CC microcytic anemia during the first year of life and ranges from
CC mild to transfusion-dependent, and transient inflammatory
CC dermatosis, often manifesting as Sweet syndrome (neutrophilic skin
CC infiltration). Note=The disease is caused by mutations affecting
CC the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the lipin family.

CLONING
Mice carrying mutations in the fatty liver dystrophy (fld) gene have
read morefeatures of human lipodystrophy (Reue et al., 2000). In the human,
lipodystrophy is a heterogeneous group of disorders characterized by
loss of body fat, fatty liver, hypertriglyceridemia, and insulin
resistance. Through positional cloning, Peterfy et al. (2001) isolated
the gene responsible for fatty liver dystrophy in mice and characterized
2 independent mutant alleles of the fld gene. They designated the gene
Lpin1 and named the novel nuclear protein which it encodes lipin.
Through database searches, Peterfy et al. (2001) identified several
mouse and human EST and genomic sequences with similarities to Lpin1.
These included 2 Lpin1-related mouse genes (Lpin2 and Lpin3) and 3 human
homologs (LPIN1 (605518), LPIN2, and LPIN3 (605520)). LPIN2 is identical
to the KIAA0249 gene identified by Nagase et al. (1996).
By PCR and Northern blot analysis, Ferguson et al. (2005) detected a
6-kb LPIN2 transcript in multiple human tissues including liver, lung,
kidney, and placenta.
GENE STRUCTURE
Ferguson et al. (2005) noted that the LPIN2 gene contains 20 exons
spanning 95 kb.
MAPPING
Using sequence databases, Peterfy et al. (2001) mapped the human LPIN2
gene to 18p. They mapped the mouse gene to chromosome 17.

*FIELD* TX
A number sign (#) is used with this entry because of evidence that
Majeed syndrome can be caused by mutation in the LPIN2 gene (605519).
CLINICAL FEATURES
Majeed et al. (1989) reported 2 brothers and a female cousin who had
chronic recurrent multifocal osteomyelitis (CRMO; 259680) and congenital
dyserythropoietic anemia (CDA); the brothers also had neutrophilic
dermatosis or Sweet syndrome (608068). The clinical course of all 3
children was similar; the unaffected parents in both families were
consanguineous.
Majeed et al. (2000) reported a fourth child with CRMO and CDA born into
the consanguineous Arab family previously reported by Majeed et al.
(1989), a brother of the female cousin. Over a period of 9 to 16 years
of follow-up, the course of CRMO in these patients was characterized by
early onset and 1 to 3 episodes per month, sometimes associated with
mild fever. The 4 children failed to thrive; height and weight were
below the 5th percentile with delayed bone age. All had significant
hepatosplenomegaly and had required blood transfusions on several
occasions. Their peripheral blood smears showed hypochromia and
microcytosis, in contrast to the normo- and macrocytosis reported in
other variants of CDA (see 224120). Majeed et al. (2000) concluded that
the combination of CRMO characterized by early onset, aggressive course,
and long duration with a new microcytic type of CDA represented a new
autosomal recessive syndrome.
Majeed et al. (2001) reported a brother and sister, born into a
consanguineous Arab family, who developed Majeed syndrome at 3 weeks and
2 months of age, respectively. The diagnosis of CRMO was confirmed by
radiography and technetium isotope bone scans; bone marrow studies
confirmed the diagnosis of CDA, which was hypochromic and microcytic on
peripheral blood smears. At age 21, the brother still had active CRMO
with frequent relapses; both patients' height and weight were below the
5th percentile. The first-cousin parents and 3 other sibs were
unaffected.
Ferguson et al. (2005) noted that although Sweet syndrome was
definitively diagnosed in only the 2 brothers reported by Majeed et al.
(1989), the 2 cousins reported by Majeed et al. (1989, 2000) in that
family had a history of rash that was consistent with Sweet syndrome.
Ferguson et al. (2005) stated that the 2 affected sibs from the second
family reported by Majeed et al. (2001) did not have Sweet syndrome, but
1 of them had a history of cutaneous pustulosis, and an obligate carrier
from that family had severe psoriasis.
