Therefore, it has been classified as a Variant of Uncertain Significance. Nucleotide substitutions within 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, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with CHEK2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects codon 148 of the CHEK2 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the CHEK2 protein. This variant also falls at the last nucleotide of exon 3, which is part of the consensus splice site for this exon.
