The recorded framework is ClinGen CHEK2 VCEP v1.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.
The applied criteria and their strengths are shown as assessed under the stated framework.
No pathogenic criterion marked as applied in the recorded assessment.
Multiple independent lines of computational evidence predict no damaging effect: REVEL score 0.046 (below the default 0.5 pathogenicity threshold), BayesDel score -0.342 (negative, strongly supporting benign), SpliceAI max delta 0.00 (no predicted splice alteration), and in silico tools from PMID:30851065 (SIFT: Tolerated, Align GVGD: C0, MutationTaster: Polymorphism). Four independent predictors converge on a benign interpretation.
No source classification-combination explanation was recorded.

NM_007194.4:c.1604G>A (p.Arg535His) is a missense variant in CHEK2 located in the C-terminal region of the protein, outside the kinase and FHA domains.
Multiple independent computational predictors (REVEL 0.046, BayesDel -0.342, SpliceAI delta 0.00, SIFT Tolerated, Align GVGD C0, MutationTaster Polymorphism) converge on a benign interpretation, satisfying BP4 at supporting benign strength.
Direct functional assessment in a yeast-based assay (Delimitsou et al. 2019, PMID:30851065) characterized this variant as benign (wild-type-like function), consistent with the computational predictions.
The variant is present in gnomAD population databases (v2.1: 63/264,906 alleles, AF=0.024%, grpmax FAF=0.16%, 1 homozygote; v4.1: 146/1,594,044 alleles, AF=0.0092%, grpmax FAF=0.11%, 2 homozygotes) with highest frequency in the South Asian subpopulation (0.20% v2.1).
In ClinVar (VariationID 128067), this variant has received a mixed classification: Likely benign by 8 clinical laboratories, Uncertain significance by 6, and Benign by 1. Review status is single-submitter (1-star) rather than expert panel.
No pathogenic ACMG/AMP criteria are met. No benign criteria are met beyond BP4 (supporting benign). The evidence is insufficient for a definitive benign classification; the variant remains a variant of uncertain significance (VUS), leaning benign based on computational and functional data.
