Labcorp Genetics (formerly Invitae), Labcorp RCV002636411 SCV002969935 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2K; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B1; Walker-Warburg congenital muscular dystrophy 2022-04-28 criteria provided, single submitter clinical testing This sequence change falls in intron 6 of the POMT1 gene. It does not directly change the encoded amino acid sequence of the POMT1 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (no rsID available, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with POMT1-related conditions. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. 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.
