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]

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Aug 14, 2024	In silico analysis indicates that this missense variant does not alter protein structure/function; Observed in individual(s) with breast cancer (PMID: 28202063); This variant is associated with the following publications: (PMID: 29056344, 28202063) -

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 25, 2024	This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 1297 of the POLE protein (p.Ser1297Leu). This variant is present in population databases (rs746585658, gnomAD 0.005%). This missense change has been observed in individual(s) with breast cancer (PMID: 28202063). ClinVar contains an entry for this variant (Variation ID: 240486). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Not Available"; Align-GVGD: "Not Available". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
