Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 13, 2022 | 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with ARHGAP31-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.009%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 18 of the ARHGAP31 protein (p.Ala18Val). - |
