Variant summary
Our verdict is Pathogenic. Variant got 17 ACMG points: 17P and 0B. PS1_Very_StrongPM1PM2PP2PP3_Strong
The NM_001165963.4(SCN1A):c.2833T>C(p.Phe945Leu) 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. Variant has been reported in ClinVar as not provided (no stars). Another nucleotide change resulting in same amino acid change has been previously reported as Likely pathogenicin ClinVar. Synonymous variant affecting the same amino acid position (i.e. F945F) has been classified as Likely benign.
