Invitae RCV001235981 SCV001408691 uncertain significance Atrial fibrillation, familial, 18 2023-12-14 criteria provided, single submitter clinical testing This sequence change affects codon 45 of the MYL4 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the MYL4 protein. This variant also falls at the last nucleotide of exon 2, which is part of the consensus splice site for this exon. 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 MYL4-related conditions. ClinVar contains an entry for this variant (Variation ID: 962172). 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.
