Variant 11-823809-C-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 2P and 11B. PM2BP4_StrongBP6_ModerateBP7BS1

The ENST00000336615.9(PNPLA2):c.873C>A(p.Pro291=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000103 in 1,601,560 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Synonymous variant affecting the same amino acid position (i.e. P291P) has been classified as Benign.

Genes affected

PNPLA2 (HGNC:30802): (patatin like phospholipase domain containing 2) This gene encodes an enzyme which catalyzes the first step in the hydrolysis of triglycerides in adipose tissue. Mutations in this gene are associated with neutral lipid storage disease with myopathy. [provided by RefSeq, Jul 2010]
