Description

This sequence change affects codon 388 of the MUTYH mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the MUTYH protein. This variant is present in population databases (rs1553126326, ExAC 0.03%). This variant has not been reported in the literature in individuals with MUTYH-related conditions. ClinVar contains an entry for this variant (Variation ID: 492001). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing, but this prediction has not been confirmed by published transcriptional studies. 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.
