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: 691275). 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 falls in intron 4 of the SYNGAP1 gene. It does not directly change the encoded amino acid sequence of the SYNGAP1 protein. It affects a nucleotide within the consensus splice site.
