Genes affected

POLE (HGNC:9177): (DNA polymerase epsilon, catalytic subunit) This gene encodes the catalytic subunit of DNA polymerase epsilon. The enzyme is involved in DNA repair and chromosomal DNA replication. Mutations in this gene have been associated with colorectal cancer 12 and facial dysmorphism, immunodeficiency, livedo, and short stature. [provided by RefSeq, Sep 2013]

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: The POLE c.755C>T (p.Ala252Val) variant involves the alteration of a conserved nucleotide. 3/4 in silico tools predict a benign outcome (Mutation Taster not captured due to low p-value). This variant was found in 10401/121392 control chromosomes (545 homozygotes) at a frequency of 0.0856811, which is 6032 times the estimated maximal expected allele frequency of a pathogenic POLE variant (0.0000142), highly suggesting this variant is a benign polymorphism. The variant has been identified in patients, but not at a significantly higher frequency than in healthy controls (Kane_Cancer Res_2014). Taken together, this variant is classified as benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as 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. -
