Labcorp Genetics (formerly Invitae), Labcorp RCV002023208 SCV002306490 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2P; Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A9 2022-11-08 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt DAG1 protein function. ClinVar contains an entry for this variant (Variation ID: 1512788). This variant has not been reported in the literature in individuals affected with DAG1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 892 of the DAG1 protein (p.Tyr892Cys).
