Evidence submitted by expert panel
Epilepsy Sodium Channel VCEP
The c.56G>A variant in SCN2A is a missense variant predicted to cause substitution of arginine by lysine at amino acid 19 (p.Arg19Lys). This variant is present at an allele frequency of 8% of the total population in gnomAD (v2.1.1), with the highest sub-population allele frequency in the East Asian population with an AF of 15%, which exceeds the threshold of 0.01% to meet the stand-alone criterion for Benign (BA1). This variant has not been reported in the literature to date in an individual with a complex neurodevelopmental disorder (PS2_not met, PM6_not met, PS4_not met). The variant has not been functionally characterized, and is not located in a pathogenic enriched region defined as a mutational hotspot (PM1_not met). In summary, this variant meets the criteria to be classified as BENIGN for AUTOSOMAL DOMINANT COMPLEX NEURODEVELOPMENTAL DISORDER based on the ACMG/AMP criteria applied, as specified by the ClinGen Epilepsy Sodium Channel VCEP: BA1 (Epilepsy Sodium Channel VCEP specifications, version 1.0; approved 6/13/23).
