Description

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.000008, PM2_M). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.734, PP3_P). A missense variant is a common mechanism associated with Scapuloperoneal syndrome (PP2_P). Therefore, this variant is classified as uncertain significance according to the recommendation of ACMG/AMP guideline.
