Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP4_Strong BP6

The NM_006231.4(POLE):c.5278G>A(p.Val1760Met) variant causes a missense change. The variant allele was found at a frequency of 0.0000608 in 1,612,036 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. V1760A) 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]

ACMG classification

Verdict is Likely_benign. Variant got -5 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0678651).
• BP6: Variant 12-132641747-C-T is Benign according to our data. Variant chr12-132641747-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 246327.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=2}.

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 any affected patients. It is classified as VUS in ClinVar (1 star) by GeneDx. It is present in ExAC at 0.07% and gnomAD at 0.1% (19 alleles - too high for gene-disease prevalence). -
