Entrez Gene Summary for PNPLA3 Gene

  • The protein encoded by this gene is a triacylglycerol lipase that mediates triacylglycerol hydrolysis in adipocytes. The encoded protein, which appears to be membrane bound, may be involved in the balance of energy usage/storage in adipocytes. [provided by RefSeq, Jul 2008]

Variants for PNPLA3 Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for PNPLA3 Gene

Polymorphic variation at position 148 influences insulin secretion levels and obesity. In obese subjects the body mass index and waist are higher in carriers of the Ile-148 allele. The Ile-148 carriers also display decreased insulin secretion in response to oral glucose tolerance test. Met-148 allele carriers are seemingly more insulin resistant at a lower body mass index

Disorders for PNPLA3 Gene


  • Non-alcoholic fatty liver disease 1 (NAFLD1) [MIM:613282]: A condition characterized by accumulation of triglycerides in the liver. It is associated with adverse metabolic consequences, including insulin resistance and dyslipidemia. In a subset of individuals, hepatic steatosis promotes an inflammatory response in the liver, referred to as steatohepatitis, which can progress to cirrhosis and liver cancer. NAFLD is the most common form of liver disease in Western countries. {ECO:0000269 PubMed:18820647, ECO:0000269 PubMed:19224197, ECO:0000269 PubMed:19738004}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
