Labcorp Genetics (formerly Invitae), Labcorp RCV002001484 SCV002274901 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2P; Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A9 2022-09-06 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 684 of the DAG1 protein (p.Asp684Gly). This variant is not present in population databases (gnomAD no frequency). 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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"). ClinVar contains an entry for this variant (Variation ID: 1489364). This variant has not been reported in the literature in individuals affected with DAG1-related conditions.
