Invitae RCV000648002 SCV000769812 uncertain significance Qualitative or quantitative defects of dysferlin 2022-06-13 criteria provided, single submitter clinical testing This sequence change affects codon 1335 of the DYSF mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the DYSF protein. This variant also falls at the last nucleotide of exon 37, which is part of the consensus splice site for this exon. This variant is present in population databases (rs773542731, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with DYSF-related conditions. ClinVar contains an entry for this variant (Variation ID: 538635). 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.
