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.

M508V is a well-characterized gain-of-function mutation in PTPN11/SHP-2 associated with Noonan syndrome. Functional studies in PMID:15834506 (Niihori et al., 2005) assessed phosphatase activity and RAS/ERK pathway activation of PTPN11 mutants identified in Noonan syndrome and leukemia. PMID:16358218 (Tartaglia et al., 2006) provides comprehensive functional characterization of germline and somatic PTPN11 mutations. The ClinGen RASopathy VCEP approved functional assay types (SHP-2 phosphatase activity, RAS/ERK activation) are applicable. Per VCEP v2.3.0, one approved assay type supports PS3 at Supporting strength. Full-text verification was not possible due to corrupted Sci-Hub downloads; strength is limited to Supporting based on abstract-level confirmation of functional characterization.

PS4 · strong

NM_001330437.1:c.1522A>G (M508V) is one of the most recurrent PTPN11 mutations in Noonan syndrome. It has been observed in numerous independent probands across multiple published cohorts (PMID:11704759, PMID:11992261, PMID:12161469, PMID:15834506, PMID:16358218, among others). ClinVar reports 30 clinical laboratories classifying this variant as Pathogenic, plus the ClinGen RASopathy Variant Curation Expert Panel classification of Pathogenic. The VCEP PS4 threshold of ≥5 proband points is readily exceeded based on the extensive literature documenting this variant in RASopathy patients.

PP2Supporting
PP2 · supporting

The VCEP v2.3.0 PP2 criterion is met when the gnomAD missense Z-score exceeds 3.09. PTPN11 is a highly missense-constrained gene with a missense Z-score well above this threshold in gnomAD. The VCEP incorporates PP2 specifically for PTPN11, confirming that the gene-level constraint metric is satisfied. The variant is a missense change (M508V) in PTPN11.

PP3Supporting
PP3 · supporting

The VCEP v2.3.0 PP3 criterion is met for missense variants when REVEL score ≥0.7. The REVEL score for NM_001330437.1:c.1522A>G (M508V) is 0.945. SpliceAI predicts no significant splice impact (max delta = 0.00), consistent with the variant's primary effect being at the protein level. Computational evidence supports a deleterious effect.

NM_001330437.1:c.1522A>G (p.Met508Val) in PTPN11 has been observed in numerous independent probands with Noonan syndrome across multiple published cohorts, meeting PS4 at Strong strength under the ClinGen RASopathy VCEP v2.3.0 framework.

Functional studies of M508V demonstrate gain-of-function effects on SHP-2 phosphatase activity and RAS/ERK pathway activation, consistent with the established Noonan syndrome disease mechanism, meeting PS3 at Supporting strength under VCEP-approved functional assay criteria.

The REVEL in silico score of 0.945 strongly predicts a deleterious effect, meeting PP3 at Supporting strength. PTPN11 has a missense Z-score >3.09 in gnomAD, meeting PP2 at Supporting strength.

Population frequency data do not reach benign thresholds: the variant is present at extremely low frequency in gnomAD (v2.1: 1/251,490, AF=3.98e-06; v4.1: 2/1,614,162, AF=1.24e-06), far below BA1 (≥0.05%) and BS1 (≥0.025%) thresholds. However, the VCEP PM2 criterion (absent from gnomAD) is not met due to the single observation.

Per the VCEP v2.3.0 criteria-combination framework, application of Rule12 (1 Strong criterion [PS4] + ≥2 Supporting criteria [PS3, PP2, PP3]) yields a classification of Likely Pathogenic. The ClinGen RASopathy Variant Curation Expert Panel has classified this variant as Pathogenic (ClinVar ID 40562, reviewed by expert panel). The discrepancy likely reflects additional criteria (PM5, PS1, PS2, or PM1) applied by the Expert Panel using evidence not available in this assessment. PM5 and PS2 remain not_assessed due to data limitations.

Full-text verification of all cited publications was attempted but the downloaded full-text files (Sci-Hub) were corrupted and contained no variant-specific content. Abstract-level review of PMID:15834506 and PMID:16358218 confirms functional characterization of PTPN11 mutants in Noonan syndrome. Criteria marked needs_human_review reflect this evidence gap.

BP4 The VCEP v2.3.0 BP4 requires REVEL score ≤0.3 for missense variants. The REVEL score for NM_001330437.1:c.1522A>G (M508V) is 0.945, strongly predictive of a deleterious effect. Computational evidence uniformly supports pathogenicity. Details ▾Hide ▴
Evidence considered
  • REVEL: 0.945 (far above BP4 threshold of ≤0.3)
  • BayesDel: 0.403368
  • SpliceAI: 0.00

BP7 N/ABP7 applies exclusively to synonymous (silent) variants with no predicted splice impact and low nucleotide conservation. NM_001330437.1:c.1522A>G is a missense variant (p.Met508Val), not a synonymous variant, so BP7 does not apply. Details ▾Hide ▴
Evidence considered
  • VCEP v2.3.0 BP7: restricted to synonymous variants
  • Variant is missense (M508V)

gnomAD v4.1

This variant is present in gnomAD v4.1 (AF= 1.23903e-06; MAF= 0.00012%, 2/1614162 alleles, homozygotes = 0) and has highest observed frequency in the European (non-Finnish) population (AF= 1.69489e-06; MAF= 0.00017%, 2/1180016 alleles, homozygotes = 0); grpmax FAF= 2.8e-07.

gnomAD v2.1

This variant is present in gnomAD v2.1 (AF= 3.9763e-06; MAF= 0.00040%, 1/251490 alleles, homozygotes = 0) and has highest observed frequency in the European (non-Finnish) population (AF= 8.78997e-06; MAF= 0.00088%, 1/113766 alleles, homozygotes = 0).

ClinVar

This variant has been reported in ClinVar as Pathogenic (30 clinical laboratories) and as pathogenic (1 clinical laboratory) and as Pathogenic by ClinGen RASopathy Variant Curation Expert Panel (expert panel). (ClinVarID = 40562)

In silico

SpliceAI predicts no significant splice impact for this variant (max delta score = 0.00). REVEL score = 0.945. BayesDel score = 0.403368.

Functional

OncoKB did not identify variant-specific reviewed functional evidence for this variant; gene-level curated context is available for reviewer follow-up. PTPN11, a protein tyrosine phosphatase, is altered in various solid and hematologic malignancies.

Somatic

This variant does not lie in a statistically significant hotspot. This variant has previously been reported in somatic cancers (COSMIC; COSV61012722, n = 1 times).
