Labcorp Genetics (formerly Invitae), Labcorp RCV003507854 SCV004331625 uncertain significance Rhabdoid tumor predisposition syndrome 2 2023-10-12 criteria provided, single submitter clinical testing This sequence change affects codon 872 of the SMARCA4 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the SMARCA4 protein. This variant also falls at the last nucleotide of exon 18, 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 SMARCA4-related conditions. 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 create or strengthen a 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.
