Invitae | RCV000823759 | SCV000964629 | uncertain significance | Developmental and epileptic encephalopathy, 14; Autosomal dominant nocturnal frontal lobe epilepsy 5 | 2023-05-20 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant  is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 665465). This variant has not been reported in the literature in individuals affected with KCNT1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 38 of the KCNT1 protein (p.Arg38Gly). |
