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.

The recorded framework is ClinGen PTPN11 VCEP v2.3.0. The criteria and strengths shown below come from the saved assessment; this page does not recalculate the classification.

The variant has been observed as de novo with confirmed maternity and paternity in multiple unrelated probands with Noonan syndrome. The ClinGen RASopathy VCEP expert panel classified this variant as Pathogenic (SCV000616373), which under the VCEP point-based PS2 scoring system (4 points = very_strong) indicates multiple confirmed de novo occurrences. The variant is recurrently reported as de novo in the foundational PTPN11-Noonan syndrome literature.

PS3 · moderate

Functional studies in two independent publications have demonstrated a damaging effect of the p.Glu139Asp substitution on SHP-2 protein function. Martinelli et al. (2008, PMID:18372317) analyzed the biochemical behavior and ligand-binding properties of E139D, demonstrating altered catalytic activity. Mueller et al. (2013, PMID:23584145) studied altered SH2-domain binding properties of E139D using quantitative mass spectrometry. These represent two different approved functional assay approaches supporting a gain-of-function effect consistent with the RASopathy disease mechanism.

The variant is significantly enriched in affected individuals compared to population controls. It is absent from gnomAD v2.1 and present at extremely low frequency in v4.1 (1/1,613,776 alleles; AF=6.2e-7). It has been reported in multiple Noonan syndrome cohorts and is classified as Pathogenic by 45 clinical laboratories in ClinVar.

The variant is absent from gnomAD v2.1 and is present at an extremely low frequency in gnomAD v4.1 (1/1,613,776 alleles; AF=6.2e-7). This meets the VCEP PM2 rule requiring the variant be absent from controls. The VCEP assigns only Supporting strength for PM2 in this framework.

PP2 · supporting

PTPN11 has a missense constraint z-score >3.09 in gnomAD, indicating a low rate of benign missense variation. This meets the VCEP PP2 criterion that missense variants in genes with high missense constraint are more likely to be pathogenic.

The REVEL score for this variant is 0.769, which meets the VCEP PP3 threshold of ≥0.7 for missense variants. This in silico prediction supports a deleterious effect on protein function. SpliceAI predicts no splicing impact (max delta = 0.00), consistent with a purely missense effect.

NM_001330437.1:c.417G>C (p.Glu139Asp) is a missense variant in PTPN11 that has been classified as Pathogenic by the ClinGen RASopathy Variant Curation Expert Panel (ClinVar variation ID 40513).

The variant has been observed as de novo with confirmed maternity and paternity in multiple unrelated probands with Noonan syndrome, meeting PS2 at Very_Strong level under the VCEP point-based scoring system (4 points).

Functional studies in two independent publications (Martinelli et al. 2008, PMID:18372317; Mueller et al. 2013, PMID:23584145) demonstrate altered SHP-2 biochemical behavior, ligand-binding properties, and SH2-domain interactions consistent with a gain-of-function mechanism, meeting PS3 at Moderate strength (two different approved assay approaches).

The variant is significantly enriched in affected individuals compared to population controls. It is absent from gnomAD v2.1 and present at extremely low frequency in gnomAD v4.1 (1/1,613,776 alleles; AF=6.2e-7), meeting PS4_Supporting and PM2_Supporting.

In silico predictions support a deleterious effect: the REVEL score is 0.769, meeting the VCEP PP3 threshold of ≥0.7. PTPN11 also has a high missense constraint z-score (>3.09), meeting PP2.

Applying the ClinGen RASopathy VCEP v2.3.0 final classification rules: the variant has PS2_Very_Strong (1) and three Supporting-level criteria (PM2_Supporting, PP2, PP3), satisfying Rule4 which requires PS2_Very_Strong plus ≥2 Supporting criteria for a Pathogenic classification.

The overall classification is Pathogenic for Noonan syndrome and related RASopathies, consistent with the ClinGen RASopathy VCEP expert panel determination.

PM5 The automated PM5 comparator search did not identify other pathogenic/likely pathogenic missense variants at codon 139, likely due to a pipeline classification issue (variant class field was null despite this being a clear missense variant). Codon 139 is a known mutational hotspot in PTPN11.
