The recorded framework is Not recorded. 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.
c.580G>C (p.Asp194His) is located in exon 4 within the STK11 serine/threonine protein kinase domain (residues 49-309). Asp194 is a highly conserved catalytic base in the kinase active site (DLKPEN motif). The residue lies in a statistically significant mutational hotspot, and no benign missense variants have been observed at this residue in gnomAD. The variant is situated in a critical, well-established functional domain where pathogenic missense variation is enriched.
NM_000455.5:c.580G>C is absent from gnomAD v2.1 (exomes) and gnomAD v4.1 (exomes + genomes), representing a combined survey of over 800,000 alleles without observation. The variant is also absent from gnomAD-Canada v1.0. This complete absence from large population databases meets PM2 at moderate strength under the generic ACMG/AMP framework (allele frequency <0.1%).
Multiple lines of computational evidence support a deleterious effect. REVEL predicts a highly damaging score of 0.943 (threshold ≥0.75). BayesDel gives a score of 0.524 (threshold >0.27 for deleterious). SpliceAI predicts no splice impact (max delta = 0.02), which does not contradict the missense pathogenicity prediction. Two independent in silico algorithms concur on a damaging prediction, meeting PP3 at supporting strength.
No benign criterion marked as applied in the recorded assessment.
gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PM1 moderate, PM2 moderate, PP3 supporting; combination = 2 moderate + 1 supporting, which maps to VUS.

NM_000455.5:c.580G>C (p.Asp194His) is located in exon 4 of STK11, within the protein kinase domain catalytic loop (DLKPEN motif), a critical functional domain.
The variant is absent from gnomAD v2.1, v4.1, and gnomAD-Canada, representing coverage of over 800,000 alleles (PM2_moderate).
Asp194 is a statistically significant hotspot residue in the kinase active site, and no benign missense variants are observed at this codon in population databases (PM1_moderate).
Multiple in silico algorithms predict a deleterious effect: REVEL score 0.943, BayesDel score 0.524 (PP3_supporting).
SpliceAI predicts no significant splice impact (max delta = 0.02), consistent with a missense mechanism rather than splicing disruption.
The variant has been observed in somatic cancers (COSMIC COSV99045288, n=3), which is consistent with a potential oncogenic role but does not directly inform germline pathogenicity.
ClinVar contains two submissions: Uncertain Significance (Invitae, SCV001518979) and Likely Pathogenic (CeGaT, SCV002498394). Neither is from an expert panel.
No de novo observations, cosegregation data, or functional studies specific to p.Asp194His were identified in the literature.
The absence of variant-specific functional data, segregation evidence, and case-control studies limits the certainty of classification.
