Description

Variant summary: MUTYH c.1000C>G (p.Pro334Ala) results in a non-conservative amino acid change in the encoded protein sequence that lies 3 nucleotides away from an exon-intron junction. Four of five in-silico tools predict a benign effect of the variant on protein function. 4/5 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 1.3e-05 in 224868 control chromosomes. This frequency is not higher than expected for a pathogenic variant in MUTYH causing MUTYH-associated Polyposis (1.3e-05 vs 0.0046), allowing no conclusion about variant significance. c.1000C>G has been reported in the literature in individuals affected with MUTYH-associated Polyposis. However, these reports do not provide unequivocal conclusions about an association of the variant with MUTYH-associated Polyposis. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014, and both classified the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as uncertain significance.
