Variant summary
Our verdict is Benign. Variant got -13 ACMG points: 1P and 14B. PP2BP4_ModerateBP6_Very_StrongBS2
The NM_001165963.4(SCN1A):c.3166A>G(p.Asn1056Asp) variant causes a missense change. The variant allele was found at a frequency of 0.000018 in 1,613,674 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 Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N1056H) has been classified as Uncertain significance.

Submissions by phenotype
Inborn genetic diseases Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Oct 13, 2017 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
