Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PP3PP5BS2
The NM_004977.3(KCNC3):c.1196C>T(p.Ser399Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000041 in 1,461,874 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. S399S) has been classified as Likely benign.
