Labcorp Genetics (formerly Invitae), Labcorp RCV001303810 SCV001493069 uncertain significance Cohen syndrome 2022-07-12 criteria provided, single submitter clinical testing This sequence change affects codon 2618 of the VPS13B mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the VPS13B protein. This variant also falls at the last nucleotide of exon 42, which is part of the consensus splice site for this exon. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with VPS13B-related conditions. ClinVar contains an entry for this variant (Variation ID: 1006724). 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.
