Labcorp Genetics (formerly Invitae), Labcorp RCV000648195 SCV000770009 uncertain significance Autosomal recessive limb-girdle muscular dystrophy type 2O; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B3 2024-10-15 criteria provided, single submitter clinical testing This sequence change affects codon 384 of the POMGNT1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the POMGNT1 protein. This variant also falls at the last nucleotide of exon 13, which is part of the consensus splice site for this exon. This variant is present in population databases (rs760312462, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with POMGNT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 538740). 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 may disrupt the consensus splice site. 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.
