Labcorp Genetics (formerly Invitae), Labcorp RCV001306649 SCV001496030 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2P; Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A9 2020-02-05 criteria provided, single submitter clinical testing 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: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with DAG1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with arginine at codon 272 of the DAG1 protein (p.Pro272Arg). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and arginine.
