Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PNPLA3 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Specifically catalyzes coenzyme A (CoA)-dependent acylation of 1-acyl-sn-glycerol 3-phosphate (2-lysophosphatidic acid/LPA) to generate phosphatidic acid (PA), an important metabolic intermediate and precursor for both triglycerides and glycerophospholipids. Does not esterify other lysophospholipids. Acyl donors are long chain (at least C16) fatty acyl-CoAs: arachidonoyl-CoA, linoleoyl-CoA, oleoyl-CoA and at a lesser extent palmitoyl-CoA (PubMed:22560221). Additionally possesses low triacylglycerol lipase and CoA-independent acylglycerol transacylase activities and thus may play a role in acyl-chain remodeling of triglycerides (PubMed:15364929, PubMed:20034933, PubMed:22560221). {ECO:0000269|PubMed:15364929, ECO:0000269|PubMed:20034933, ECO:0000269|PubMed:22560221}.
• Disease: DISEASE: 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, ECO:0000269|PubMed:27288299}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
