Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4BP6

The NM_006231.4(POLE):c.5382C>G(p.Ile1794Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000378 in 1,613,660 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I1794F) has been classified as Uncertain significance.

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]

Benign:2

Likely benign, criteria provided, single submitter	clinical testing	GeneDx	Mar 29, 2018	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. -

The p.Ile1794Met variant in POLE has not been previously reported in individuals with colorectal cancer but has been identified in 8/66456 of European chromosom es by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; db SNP rs368364666). Computational prediction tools and conservation analysis do n ot provide strong support for or against an impact to the protein. In summary, t he clinical significance of the p.Ile1794Met variant is uncertain. -
