Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4BP6BS1

The NM_020376.4(PNPLA2):c.236G>A(p.Arg79Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000641 in 1,613,886 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R79W) 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: Likely_benign. The variant received -6 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.28251272).

BP6

Variant 11-821676-G-A is Benign according to our data. Variant chr11-821676-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 465789.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000466 (71/152326) while in subpopulation SAS AF = 0.00104 (5/4828). AF 95% confidence interval is 0.000612. There are 0 homozygotes in GnomAd4. There are 31 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
