Variant summary: POLE c.555C>T results in a synonymous change. 5/5 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 7.2e-05 in 277132 control chromosomes (gnomAD). The observed variant frequency is approximately 5 fold of the estimated maximal expected allele frequency for a pathogenic variant in POLE causing Colorectal Cancer phenotype (1.4e-05), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.555C>T in individuals affected with Colorectal Cancer and no experimental evidence demonstrating its impact on protein function have been reported. Three clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as benign. -

Hereditary cancer-predisposing syndrome    Benign:1 
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
