Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 1P and 1B. PP3BS1_Supporting

The NM_020376.4(PNPLA2):c.338G>A(p.Arg113His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000203 in 1,613,938 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R113C) has been classified as Uncertain significance.

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]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.824

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000184 (28/152306) while in subpopulation EAS AF = 0.000772 (4/5184). AF 95% confidence interval is 0.000263. There are 0 homozygotes in GnomAd4. There are 18 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
