Genes affected

PNPLA5 (HGNC:24888): (patatin like phospholipase domain containing 5) This gene is a member of the patatin-like phospholipase family; its encoded protein has been shown to inhibit transacylation. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Apr 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.95).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.971 is higher than 0.05.
