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. -

Variant summary: c.4444+4T>A in POLE gene is an intronic change that involves a non-conserved nucleotide. 5/5 programs in Alamut predict that this variant enhances the donor cite, however no functional studies supporting this notion were published at the time of evaluation. The variant is present in the control population dataset of ExAC at frequency of 0.0624 (7579/121388 chrs tested), predominantly in individuals of European descent (0.0819; 5568/66728 chrs tested) including numerous homozygous occurrences. The observed frequencies exceed the maximum expected allele frequency for a pathogenic variant of 0.0014%, suggesting that it is a benign polymorphism. The variant of interest has not, to our knowledge, been reported in affected individuals in published reports or cited by reputable databases/clinical laboratory. Taking together, based on the prevalence of this variant in general population the variant was classified as Benign. -

Ambry Genetics
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. -
