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]

Variant summary: POLE c.3718G>A (p.Glu1240Lys) results in a conservative amino acid change in the encoded protein sequence. Algorithms developed to predict the effect of missense changes on protein structure and function all suggest that this variant is likely to be tolerated. The variant allele was found at a frequency of 0.00076 in 251418 control chromosomes, predominantly at a frequency of 0.0015 within the Non-Finnish European subpopulation in the gnomAD database. The observed variant frequency within Non-Finnish European control individuals in the gnomAD database is approximately 1.34 fold of the estimated maximal expected allele frequency for a pathogenic variant in POLE causing Facial Dysmorphism, Immunodeficiency, Livedo, And Short Stature phenotype (0.0011). To our knowledge, no occurrence of c.3718G>A in individuals affected with Facial Dysmorphism, Immunodeficiency, Livedo, And Short Stature and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 240475). Based on the evidence outlined above, the variant was classified as likely benign. -

Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: This variant has not been reported in affected individuals. It is classified in ClinVar with 1 star as Likely benign by Invitae and VUS by GeneDx. It is present in ExAC at a MaxMAF of 0.15% (high for disease incidence and gene contribution). It is predicted to be benign by multiple prediction tools. Mouse and Rat have a Lysine at this position. -

The POLE c.3718G>A; p.Glu1240Lys variant (rs113594027) is reported in the literature in at least one individual with advanced cancer (Mandelker 2017), and reported as a somatic mutation in an individual with glioblastoma (Jue 2019). This variant is also reported in the ClinVar database (Variation ID: 240475). It is found in the general population with an overall allele frequency of 0.07% (206/282824 alleles) in the Genome Aggregation Database. The glutamate at codon 1240 is weakly conserved, but computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.17). Additionally, this variant is not located in the exonuclease domain (Parkash 2019), and gene-disease association has not been established for variants outside of the exonuclease domain (Seifert 2019). However, due to limited information, the clinical significance of this variant is uncertain at this time. Jue TR et al.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant is denoted POLE c.3718G>A at the cDNA level, p.Glu1240Lys (E1240K) at the protein level, and results in the change of a Glutamic Acid to a Lysine (GAG>AAG). This variant has been observed in at least one individual with advanced cancer (Mandelker 2017). POLE Glu1240Lys was observed at an allele frequency of 0.15% (190/126,656 ) in individuals of European (Non-Finnish) ancestry in large population cohorts (Lek 2016). This variant is not located in a known functional domain. In-silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function. Based on currently available evidence, it is unclear whether POLE Glu1240Lys is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. -

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. -
