Labcorp Genetics (formerly Invitae), Labcorp RCV002776015 SCV003030197 uncertain significance Developmental and epileptic encephalopathy, 36 2023-10-07 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 905 of the ALG13 protein (p.Tyr905Cys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ALG13-related conditions. ClinVar contains an entry for this variant (Variation ID: 1987478). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Not Available". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
