About KRAS

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 ClinGen KRAS VCEP v2.3.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.

Recorded applied criteria

The applied criteria and their strengths are shown as assessed under the stated framework.

Pathogenic evidence criteria: 5 Benign evidence criteria: 0
Pathogenic criteria applied · 5
PS2Moderate
PS2 · moderate

One de novo observation confirmed by parental genotyping in an infant with Noonan syndrome and lethal hypertrophic cardiomyopathy (Nosan et al. 2013). Per RASopathy VCEP PS2 rules, 1 de novo point confers Moderate strength.

PS4Supporting
PS4 · supporting

One well-documented RASopathy proband identified — an infant with Noonan syndrome, dysmorphic features, and lethal HCM harboring a de novo G60V variant (Nosan et al. 2013). Per VCEP PS4 point-based rules, ≥1 point confers Supporting strength. The variant is also reported in ClinVar as Pathogenic/Likely Pathogenic by 7 clinical laboratories.

PM1Moderate
PM1 · moderate

p.Gly60 is located within the Switch II (SW2) domain (amino acids 57–64), a critical and well-established functional domain per RASopathy VCEP specifications. SW2 is one of four domains (P-loop, SW1, SW2, SAK) approved for PM1 application at Moderate strength.

PM5Moderate
PM5 · moderate

At least two different pathogenic missense changes have been reported at codon 60 — p.Gly60Ser and p.Gly60Arg — in individuals with Noonan syndrome and cardio-facio-cutaneous syndrome (cited in Nosan et al. 2013, referencing Kratz et al. 2009 and Niihori et al. 2006). Per VCEP PM5 rules, ≥1 pathogenic residue change at the same codon confers Moderate strength.

PP3Supporting
PP3 · supporting

REVEL score of 0.879 exceeds the VCEP threshold of ≥0.7 for PP3 at Supporting strength. SpliceAI max delta score is 0.25, indicating minimal predicted splicing impact, which does not alter the REVEL-based assessment.

Benign criteria applied · 0

No benign criterion marked as applied in the recorded assessment.

Recorded classification: Likely pathogenic

ClinGen RASopathy Expert Panel Specifications to the ACMG/AMP Variant Interpretation Guidelines for KRAS Version 2.3.0 v2.3.0 criteria-combination framework: matched Rule13 (Pathogenic.Moderate >=3) with applied criteria: PS2 moderate, PS4 supporting, PM1 moderate, PM5 moderate, PP3 supporting; maps to Likely Pathogenic.

NM_033360.3:c.179G>T (p.Gly60Val) is a missense variant in KRAS identified in a single de novo proband with Noonan syndrome and lethal hypertrophic cardiomyopathy (Nosan et al. 2013).

The variant affects Gly60, which resides in the Switch II domain (AA 57–64), a critical functional domain per RASopathy VCEP specifications (PM1_Moderate).

At least two different pathogenic missense changes (p.Gly60Ser, p.Gly60Arg) have been reported at the same codon in RASopathy patients, satisfying PM5 at Moderate strength.

Parental genotyping confirmed the variant occurred de novo, meeting PS2 at Moderate strength (1 de novo point per VCEP rules).

The variant is observed in a single RASopathy proband, meeting PS4 at Supporting strength (≥1 point per VCEP rules).

REVEL in silico score of 0.879 exceeds the VCEP threshold of ≥0.7, meeting PP3 at Supporting strength.

The variant is present at extremely low frequency in gnomAD (v2.1: 1/251,328; v4.1: 3/1,614,068), which is below benign population thresholds but above the PM2 absence requirement.

Applying the RASopathy VCEP classification rules: three Moderate criteria (PS2_Moderate, PM1, PM5) plus two Supporting criteria (PS4_Supporting, PP3) are met. Per VCEP Rule13, ≥3 Moderate criteria yields a classification of Likely Pathogenic.
