Labcorp Genetics (formerly Invitae), Labcorp RCV001319006 SCV001509730 uncertain significance Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A13 2020-06-27 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with B4GAT1-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces proline with serine at codon 51 of the B4GAT1 protein (p.Pro51Ser). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and serine. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
