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]

The p.Arg1631Leu variant in POLE has not been previously reported in individuals with colorectal cancer but has been identified in 1/66346 of European chromosom es by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; db SNP rs775590365). Computational prediction tools and conservation analysis do no t provide strong support for or against an impact to the protein. In summary, th e clinical significance of the p.Arg1631Leu variant is uncertain. -

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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 517161). This variant is present in population databases (rs775590365, ExAC 0.002%). This sequence change replaces arginine with leucine at codon 1631 of the POLE protein (p.Arg1631Leu). The arginine residue is highly conserved and there is a moderate physicochemical difference between arginine and leucine. -
