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: 373940). This variant has not been reported in the literature in individuals affected with SYNGAP1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change affects codon 705 of the SYNGAP1 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the SYNGAP1 protein. This variant also falls at the last nucleotide of exon 12, which is part of the consensus splice site for this exon. |
