Genes affected
LPIN2 (HGNC:14450): (lipin 2) Mouse studies suggest that this gene functions during normal adipose tissue development and may play a role in human triglyceride metabolism. This gene represents a candidate gene for human lipodystrophy, characterized by loss of body fat, fatty liver, hypertriglyceridemia, and insulin resistance. [provided by RefSeq, Jul 2008]

The LPIN2 c.1510C>T; p.Leu504Phe variant (rs104895500), has been reported in the literature in two individuals with suspected familial Mediterranean fever, but with alternative molecular explanations for disease (Bozgeyik 2020). The variant has also been reported in an individual with psoriasis (see link below). The variant is listed in the ClinVar database (Variation ID: 97814) and is reported in the general population with an overall allele frequency of 0.3% (724/282,640 alleles, including 3 homozygotes) in the Genome Aggregation Database. Computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.675). Due to limited information, the clinical significance of the p.Leu504Phe variant is uncertain at this time.

Significance:Likely benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

LPIN2 NM_014646.2 exon 10 p.Leu504Phe (c.1510C>T): This variant has not been reported in the literature but has been reported in 1 individual with psoriasis in the Infevers database (https://infevers.umai-montpellier.fr/web/detail_mutation.php). This variant is present in 0.3% (470/129044) of European alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/18-2929103-G-A). This variant is present in ClinVar (Variation ID:97814). Evolutionary conservation suggests that this variant may impact the protein; computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
