Labcorp Genetics (formerly Invitae), Labcorp RCV003077828 SCV003461616 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2K; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B1; Walker-Warburg congenital muscular dystrophy 2022-07-14 criteria provided, single submitter clinical testing This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 719 of the POMT1 protein (p.Leu719Phe). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with POMT1-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.
