Variant summary
Our verdict is Pathogenic. Variant got 17 ACMG points: 17P and 0B. PM1PM2PP2PP3_StrongPP5_Very_Strong
The NM_001040142.2(SCN2A):c.2687C>T(p.Ala896Val) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A896S) has been classified as Uncertain significance.
