Invitae RCV001238518 SCV001411335 uncertain significance Baller-Gerold syndrome 2022-12-23 criteria provided, single submitter clinical testing This sequence change affects codon 540 of the RECQL4 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the RECQL4 protein. This variant also falls at the last nucleotide of exon 9, which is part of the consensus splice site for this exon. 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. 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. ClinVar contains an entry for this variant (Variation ID: 964323). This variant has not been reported in the literature in individuals affected with RECQL4-related conditions. This variant is not present in population databases (gnomAD no frequency).
