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]

Majeed syndrome Pathogenic:2
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 28, 2023This sequence change creates a premature translational stop signal (p.Arg157*) in the LPIN2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in LPIN2 are known to be pathogenic (PMID: 15994876, 23087183). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with LPIN2-related conditions. ClinVar contains an entry for this variant (Variation ID: 548484). For these reasons, this variant has been classified as Pathogenic. -
