Invitae | RCV000533573 | SCV000648326 | uncertain significance | Congenital muscular dystrophy due to integrin alpha-7 deficiency | 2022-08-16 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine 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. ClinVar contains an entry for this variant (Variation ID: 470577). This variant has not been reported in the literature in individuals affected with ITGA7-related conditions. This variant is present in population databases (rs753351732, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 952 of the ITGA7 protein (p.Arg952Gln). |
