NM_006164.4:c.100C>G (p.Arg34Gly) is a missense variant in exon 2 of NFE2L2. It is absent from gnomAD v2.1 and v4.1 population databases (PM2_Supporting).1 The variant is located at codon 34 within the Neh2 domain (residues 16–89), the KEAP1-binding degron that is a critical and well-established functional domain. Arg34 is a statistically significant cancer hotspot residue, and other missense alterations at this codon (R34Q, R34P) are recurrently observed in NSCLC and other cancers with no benign variation at this codon (PM1).2 The variant has been reported in COSMIC (COSV67960061, n=42) as a somatic mutation. OncoKB classifies it as Likely Oncogenic (somatic context). These somatic observations do not directly inform germline pathogenicity under ACMG/AMP.3 In silico predictions are equivocal: REVEL score 0.543 (borderline), BayesDel score 0.170 (low), and SpliceAI max delta 0.00. These do not meet the threshold for PP3 or BP4.4 No functional studies, case-control data, de novo observations, segregation data, or authoritative germline classifications are available for this variant. The majority of criteria cannot be assessed. Applying the generic ACMG/AMP 2015 combination rules: PM1 (moderate) + PM2_Supporting (supporting) = 1 moderate + 1 supporting. This is insufficient for a Likely Pathogenic classification (requires 2 moderate, or 1 strong + 1 moderate, or 1 strong + ≥2 supporting). No benign criteria are met. The variant is classified as a Variant of Uncertain Significance (VUS).5
