Invitae RCV000798327 SCV000937937 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2P; Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A9 2021-08-31 criteria provided, single submitter clinical testing This sequence change replaces threonine with proline at codon 846 of the DAG1 protein (p.Thr846Pro). The threonine residue is moderately conserved and there is a small physicochemical difference between threonine and proline. This variant is present in population databases (rs775365808, ExAC 0.005%). This variant has not been reported in the literature in individuals affected with DAG1-related conditions. 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"). 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.
