11-823586-C-A

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 3P and 2B. PM2PP3BP6_Moderate

The NM_020376.4(PNPLA2):​c.756C>A​(p.Asn252Lys) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000362 in 1,381,024 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely benign (★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin Lovd.

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]
