NM_006231.3:c.4735C>T (p.Arg1579Cys) is a missense variant in the C-terminal polymerase domain of POLE, distant from the exonuclease domain (residues 1-466) where established pathogenic missense variants cluster.1 This variant is present at very low frequency in population databases: gnomAD v2.1 at 0.00319% (1/31,386 alleles), gnomAD v4.1 at 0.00050% (8/1,613,270 alleles), and absent from gnomAD-Canada, meeting PM2 at supporting strength.2 Under the León-Castillo et al. 2020 custom POLE framework, this variant does not qualify for PM1 (not an exonuclease-domain hotspot), PS4 (not a recurrent pathogenic variant in endometrial carcinoma cohorts), PP3 (absent from supplementary in silico tables), or BP4 (absent from supplementary in silico tables).3 Computational predictors are mixed and do not converge on a pathogenic signal: REVEL 0.412 (intermediate), BayesDel 0.071 (benign-leaning), SpliceAI max delta 0.20 (borderline). PP3 and BP4 are not met.4 This variant is reported in ClinVar (VariationID 405672) as 'Uncertain significance' by three clinical laboratories. The associated publications (PMID:25394175, a cancer genetics referral guideline, and PMID:28492532, the Sherloc classification framework) do not provide variant-specific evidence for NM_006231.3:c.4735C>T.5 No functional studies, segregation data, de novo observations, or case-control studies are available for this variant. All remaining pathogenic criteria (PS1-PS5, PM1, PM5-PM6, PP1-PP5) and benign criteria (BA1, BS1-BS4, BP1-BP6) are either not met or not applicable.6 With only PM2_Supporting met, the overall classification is Uncertain Significance (VUS) per ACMG/AMP 2015 guidelines: insufficient evidence to classify as pathogenic or benign.7
