Variant summary
Our verdict is Benign. Variant got -12 ACMG points: 1P and 13B. PP2BP4_StrongBP6BS1BS2
The NM_006922.4(SCN3A):āc.2077A>Gā(p.Met693Val) variant causes a missense change. The variant allele was found at a frequency of 0.000172 in 1,613,980 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M693T) has been classified as Uncertain significance.
