Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 1P and 6B. PP3BP4BP6BS1

The NM_006231.4(POLE):c.2540G>A(p.Arg847Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000235 in 1,613,942 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. R847W) 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]

PP3

Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, Cadd, Dann, Eigen, FATHMM_MKL, MutationAssessor, phyloP100way_vertebrate, PrimateAI [when BayesDel_addAF, max_spliceai, M_CAP, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.3225203).

BP6

Variant 12-132664391-C-T is Benign according to our data. Variant chr12-132664391-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 473537.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000263 (4/152238) while in subpopulation EAS AF = 0.000773 (4/5174). AF 95% confidence interval is 0.000263. There are 0 homozygotes in GnomAd4. There are 2 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as likely 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. -
