About MLH3

No gene-level summary was recorded for this case.

LYFE Sciences is an AI system, and it can make mistakes. Criteria may be applied incorrectly, sources may be misread, and a confident-looking classification can still be wrong. Double-check every criterion and its underlying evidence before relying on any call.
01The reasoning

How it was classified

The recorded framework is Not recorded. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.

Multiple lines of computational evidence suggest no impact on the gene product: REVEL score 0.068 (strongly benign-leaning), BayesDel score -0.421 (benign-leaning), and SpliceAI max delta score 0.04 (no predicted splicing impact). All three concordant in silico predictors support a benign interpretation.

Recorded classification: Uncertain significance

gene-specific framework lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: BP4 supporting benign; combination = 1 supporting benign, which maps to VUS.

Met Not met Not assessed Not applicable

NM_001040108.2:c.3637G>A (p.Glu1213Lys) is a missense variant in exon 6 of MLH3, a mismatch repair gene associated with Lynch syndrome and polyposis predisposition.

This variant is present in gnomAD population databases at low frequency: v2.1 AF=0.0113% (32/282,848 alleles) and v4.1 AF=0.0144% (232/1,612,714 alleles), with no homozygotes observed. It does not meet BA1 (>1%), BS1 (>0.3%), or PM2 (absent/extremely low) population frequency thresholds.

ClinVar reports this variant as Uncertain Significance based on submissions from 5 clinical laboratories (ClinVar variation ID 847280). No expert panel review or pathogenic classification is available.

Multiple in silico predictors concordantly suggest a benign effect: REVEL score 0.068, BayesDel score -0.421, and SpliceAI max delta 0.04, supporting BP4 (supporting benign).

No variant-specific functional studies, segregation data, de novo occurrences, case-control enrichment, or pathogenic comparator variants at the same residue were identified. No publications specifically mention this variant.

The only met criterion is BP4 (supporting benign). No pathogenic or other benign criteria are met. The evidence is insufficient to classify this variant beyond Uncertain Significance under generic ACMG/AMP 2015 rules.
