<p>Mice carrying mutations in the fatty liver dystrophy (fld) gene have features 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). </p><p>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. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
