Invitae | RCV000541215 | SCV000638723 | uncertain significance | Generalized epilepsy-paroxysmal dyskinesia syndrome | 2022-07-11 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with KCNMA1-related conditions. 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 464303). This variant is present in population databases (rs779829350, gnomAD 0.004%). This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 223 of the KCNMA1 protein (p.Val223Met). |
