RCV000640508 | SCV000762100 | uncertain significance | X-linked myopathy with excessive autophagy | 2020-11-11 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class 0"). 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. This variant has not been reported in the literature in individuals with VMA21-related disease. This sequence change replaces alanine with valine at codon 8 of the VMA21 protein (p.Ala8Val). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and valine. While this variant is not present in population databases, the frequency information is unreliable, as metrics indicate poor data quality at this position in the ExAC database. |
