About PTPN11

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 PTPN11 VCEP v1.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.

SHP2 G60V demonstrated increased basal phosphatase activity compared to wild-type SHP2 in a quantitative DiFMUP-based phosphatase assay (PMID:30375388). This assay type (SHP-2 Phosphatase Activity) is an approved functional assay for PTPN11 per the RASopathy VCEP supplemental material. The VCEP spreadsheet assigns PS3_Supporting strength for approved functional studies. G60V showed intermediate activation between F285S and S502P/E76K and conferred resistance to allosteric inhibition by SHP099 in cellular assays, consistent with a gain-of-function mechanism.

PM1Moderate
PM1 · moderate

Gly60 is located in the N-SH2 domain of SHP2, a critical functional domain that forms the autoinhibitory interface with the PTP domain. Multiple pathogenic missense changes have been reported at this residue (G60A, G60C, G60V), and disruption of Gly60 destabilizes the autoinhibited conformation, leading to constitutive phosphatase activation. The N-SH2 domain is a well-established critical functional domain in SHP2.

NM_002834.4:c.179G>T is completely absent from gnomAD v2.1 (exomes), gnomAD v4.1 (exomes), and gnomAD-Canada v1.0 (genomes), meeting the VCEP requirement of complete absence from all population databases.

PM5Moderate
PM5 · moderate

A different missense change at the same residue, Gly60Ala (c.179G>C, p.Gly60Ala), has been previously reported as a pathogenic variant in Noonan syndrome (PMID:11992261). Both G60A and G60V are non-conservative substitutions at a glycine residue critical to the autoinhibitory interface. Under the RASopathy VCEP, one established pathogenic missense at the same residue qualifies for PM5 at moderate strength.

PP2Supporting
PP2 · supporting

The RASopathy VCEP explicitly states that PP2 is applicable to all RASopathy genes described and curated in the specification. PTPN11 is a RASopathy gene, and c.179G>T is a missense variant in a gene where missense variants are a common mechanism of disease.

PP3Supporting
PP3 · supporting

Multiple lines of computational evidence support a deleterious effect: REVEL score of 0.931 (strongly deleterious) and BayesDel score of 0.596 (deleterious). Both in silico predictors independently suggest a damaging effect on the gene product. SpliceAI predicts no significant splice impact (max delta score 0.05), indicating the effect is at the protein level.

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 Version 1.0 v1.0 lacked a usable explicit final combination framework, so generic ACMG/AMP 2015 final-combination rules were applied as fallback; applied criteria: PS3 supporting, PM1 moderate, PM2 moderate, PM5 moderate, PP2 supporting, PP3 supporting; combination = 3 moderate + 3 supporting, which maps to Likely Pathogenic.

NM_002834.4:c.179G>T (p.Gly60Val) in PTPN11 is a missense variant in the N-SH2 domain, a critical functional domain that regulates SHP2 autoinhibition.

This variant is completely absent from gnomAD v2.1, v4.1, and gnomAD-Canada population databases (PM2).

Functional studies demonstrate that SHP2 G60V exhibits increased basal phosphatase activity compared to wild-type, consistent with a gain-of-function mechanism in RASopathies (PS3_Supporting).

The variant is located at a residue (Gly60) within the N-SH2 domain where multiple pathogenic missense changes have been reported (PM1).

A different pathogenic missense change at the same residue, Gly60Ala (c.179G>C), has been reported in Noonan syndrome (PM5).

Multiple in silico predictors support a deleterious effect: REVEL score 0.931 and BayesDel score 0.596 (PP3).

PP2 is applicable per the RASopathy VCEP specification for all curated RASopathy genes (PP2).

This variant has been reported in ClinVar as Pathogenic by 9 clinical laboratories and Likely pathogenic by 2 clinical laboratories (ClinVar variation ID 55797).
