Genes affected
PNPLA3 (HGNC:18590): (patatin like phospholipase domain containing 3) 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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 19, 2023The c.115G>T (p.D39Y) alteration is located in exon 1 (coding exon 1) of the PNPLA3 gene. This alteration results from a G to T substitution at nucleotide position 115, causing the aspartic acid (D) at amino acid position 39 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
