This summary comes from the ClinGen Evidence Repository: The c.794G>A p.Arg265Gln variant in PTPN11 has been reported as a confirmed de novo occurrence in at least 2 patients with clinical features of a RASopathy (PS2_VeryStrong; GeneDx, Partners LMM, Institute of Human Genetics, Otto von Guericke University Magdeburg, APHP-Robert Debré Hospital internal data; GTR ID's:26957, 21766, 506381, 28338; ClinVar SCV000203366.6; SCV000061320.5; SCV000057406.11; SCV000207688.1). The variant has been reported in the literature to segregate with clinical features of a RASopathy in at least 3 family members (PP1; APHP-Robert Debré Hospital internal data; GTR ID: 28338). The p.Arg265Gln variant has been identified in 2 independent occurrences in patients with a RASopathy (PS4_Moderate; GeneDx, LMM, Institute of Human Genetics, Otto von Guericke University Magdeburg, APHP-Robert Debré Hospital internal data; GTR Lab ID: 26957, 21766, 506381, 28338; SCV000203366.6; SCV000061320.5; SCV000057406.11; SCV000207688.1). In vitro functional studies provide some evidence that the p.Arg265Gln variant may impact protein function (PS3; PMID 28074573). Furthermore, the variant is in a location that has been defined by the ClinGen RASopathy Expert Panel to be a mutational hotspot or domain of PTPN11 (PM1; PMID 29493581). The variant is located in the PTPN11 gene, which has been defined by the ClinGen RASopathy Expert Panel as a gene with a low rate of benign missense variants and pathogenic missense variants are common (PP2; PMID:29493581). In summary, this variant meets criteria to be classified as pathogenic for RASopathies in an autosomal dominant manner. ACMG/AMP criteria applied: PS2_VeryStrong, PP1, PS4_Moderate, PS3, PM1, PP2.

Pathogenic, criteria provided, single submitter | clinical testing | Pittsburgh Clinical Genomics Laboratory, University of Pittsburgh Medical Center | Mar 17, 2023 | This sequence variant is a single nucleotide substitution (G>A) at coding nucleotide position 794 of the PTPN11 gene which results in an arginine to glutamine amino acid change at residue 265 in the PTPN11 protein. This is a previously reported variant (ClinVar) which has been observed as a de novo or familial variant in multiple individuals with Noon syndrome (PMID: 25862627, 28074573). This variant is rare in the gnomAD control population dataset (8/247274 alleles or 0.003%). Multiple bioinformatic tools predict that this glutamic acid to glutamine amino acid change is likely to be damaging, and arginine is conserved at this protein position in all vertebrate species examined. Altering the Arg265 amino increases phosphatase activity in vitro (PMID: 28074573), and the Arg265 residue is part of a salt bridge with Glu76 (PMID: 21365683). This variant has been classified as Pathogenic by the ClinGen RASopathy Expert Panel (Accession: SCV000616412.3). Given the evidence, we consider this variant to be pathogenic.

Pathogenic, criteria provided, single submitter | clinical testing | ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories | Feb 07, 2023 | The PTPN11 c.794G>A; p.Arg265Gln variant (rs376607329) is reported in the literature in multiple individuals affected with Noonan syndrome (Chan 2006, Pannone 2017). This variant is also reported in ClinVar (Variation ID: 40522). This variant is only observed on eight alleles in the Genome Aggregation Database, indicating it is not a common polymorphism. Computational analyses predict that this variant is deleterious (REVEL: 0.814). Additionally, this codon is considered to be a hotspot by the ClinGen RASopathy expert panel (Gelb 2018). Functional analyses of the variant protein show gain of function (Pannone 2017), and structural studies show that arginine 265 is likely a critical mediator of interactions between the catalytic PTP domain and the regulatory N-terminal SH2 domain (Darian 2011, Hof 1998). Based on available information, this variant is considered to be pathogenic. References: Chan D et al. A clinical and molecular study of 51 Chinese families with Noonan syndrome.

Pathogenic, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Jun 12, 2024 | The PTPN11 c.794G>A variant is predicted to result in the amino acid substitution p.Arg265Gln. This variant has been reported in multiple unrelated individuals with Noonan syndrome and was shown to be a de novo event in at least two cases (Fokstuen et al. 2016. PubMed ID: 27353043; Pannone et al. 2017. PubMed ID: 28074573). It has also been reported in an individual with isolated short stature (Freire et al. 2019. PubMed ID: 30602027) and reported to segregate in multiple individuals from a single family with a Noonan-like presentation; however cardiac features were not present in all members (Ranza et al. 2020. PubMed ID: 32233106, Family A). Pathogenic variants in PTPN11 act in a gain-of-function manner by causing an upregulation of the RAS pathway. Consistent with this mechanism, functional studies demonstrated the p.Arg265Gln variant leads to elevated levels of ERK phosphorylation (Pannone et al. 2017. PubMed ID: 28074573). This variant is reported in 0.0063% of alleles in individuals of European (Non-Finnish) descent in gnomAD, and multiple clinical labs have interpreted this variant as likely pathogenic or pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/40522/). This variant is interpreted as pathogenic. - |

Pathogenic, reviewed by expert panel | curation | ClinGen RASopathy Variant Curation Expert Panel | Apr 03, 2017 | The c.794G>A p.Arg265Gln variant in PTPN11 has been reported as a confirmed de novo occurrence in at least 2 patients with clinical features of a RASopathy (PS2_VeryStrong; GeneDx, Partners LMM, Institute of Human Genetics, Otto von Guericke University Magdeburg, APHP-Robert Debré Hospital internal data; GTR ID's:26957, 21766, 506381, 28338; ClinVar SCV000203366.6; SCV000061320.5; SCV000057406.11; SCV000207688.1). The variant has been reported in the literature to segregate with clinical features of a RASopathy in at least 3 family members (PP1; APHP-Robert Debré Hospital internal data; GTR ID: 28338). The p.Arg265Gln variant has been identified in 2 independent occurrences in patients with a RASopathy (PS4_Moderate; GeneDx, LMM, Institute of Human Genetics, Otto von Guericke University Magdeburg, APHP-Robert Debré Hospital internal data; GTR Lab ID: 26957, 21766, 506381, 28338; SCV000203366.6; SCV000061320.5; SCV000057406.11; SCV000207688.1). In vitro functional studies provide some evidence that the p.Arg265Gln variant may impact protein function (PS3; PMID 28074573). Furthermore, the variant is in a location that has been defined by the ClinGen RASopathy Expert Panel to be a mutational hotspot or domain of PTPN11 (PM1; PMID 29493581). The variant is located in the PTPN11 gene, which has been defined by the ClinGen RASopathy Expert Panel as a gene with a low rate of benign missense variants and pathogenic missense variants are common (PP2; PMID: 29493581). In summary, this variant meets criteria to be classified as pathogenic for RASopathies in an autosomal dominant manner.

Pathogenic, criteria provided, single submitter | clinical testing | Center for Genomics, Ann and Robert H. Lurie Children's Hospital of Chicago | Dec 09, 2022 | This variant has been reported in the literature and in ClinVar in numerous patients with features consistent with or suggestive of a RASopathy; this includes as de novo in several instances, and it has been shown to segregate with disease in many similarly affected family members (Selected publications: Pannone 2017 PMID: 28074573; Qiao 2020 PMID: 32719394; Ranza 2020 PMID: 32233106; Sentchordi-Montané 2021 PMID: 34516402; ClinVar Variation ID: 40522). It is present in the Genome Aggregation Database (Highest reported MAF: 0.006% [7/110252]; https://gnomad.broadinstitute.org/variant/12-112910785-G-A?dataset=gnomad_r2_1). This has been classified as pathogenic by the ClinGen RASopathy Variant Curation Expert Panel (VCEP) (ClinVar Variation ID: 40522). Of note, this variant appears to be associated with a milder or even potentially distinct phenotype compared to what is typically seen in individuals with pathogenic variants in this gene (Gelb 2018 PMID: 29493581; Ranza 2020 PMID: 32233106; Sentchordi-Montané 2021 PMID: 34516402). Functional studies have suggested that this variant impacts the encoded protein and one or more of its signaling pathways (Pannone 2017 PMID: 28074573; Ranza 2020 PMID: 32233106). The ClinGen RASopathy VCEP concluded that this residue is functionally important and is considered a mutational hotspot; additionally, missense variation in the PTPN11 gene is a very common mechanism of disease (Gelb 2018 PMID: 29493581). Evolutionary conservation and computational prediction tools support that this variant is likely to impact the protein. In summary, this variant is classified as pathogenic. - |

RASopathy Pathogenic:2
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Aug 14, 2023 | Variant summary: PTPN11 c.794G>A (p.Arg265Gln) results in a conservative amino acid change located in the Tyrosine-specific protein phosphatase, PTPase domain (IPR000242) of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 3.2e-05 in 247274 control chromosomes (gnomAD). c.794G>A has been reported in the literature in individuals affected with Noonan Syndrome and in at least one individual the variant was observed to be de novo (examples: Forkstuen_2016, Pannone_2017). These data indicate that the variant is likely to be associated with disease. At least one publication reports experimental evidence that R265Q enhances ERK phosphorylation supporting an activating role on MAPK signaling (Pannone_2017). The following publications have been ascertained in the context of this evaluation (PMID: 27353043, 28074573). Twenty three submitters (including ClinGen RASopathy Variant Curation Expert Panel) have cited clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 29, 2024 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 265 of the PTPN11 protein (p.Arg265Gln). This variant is present in population databases (rs376607329, gnomAD 0.006%). This missense change has been observed in individual(s) with clinical features of Noonan syndrome (PMID: 27353043, 28074573). In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 40522). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt PTPN11 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects PTPN11 function (PMID: 28074573). For these reasons, this variant has been classified as Pathogenic. - |
Cardiovascular phenotype Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 11, 2022 | The p.R265Q pathogenic mutation (also known as c.794G>A), located in coding exon 7 of the PTPN11 gene, results from a G to A substitution at nucleotide position 794. The arginine at codon 265 is replaced by glutamine, an amino acid with highly similar properties. This mutation has been detected in multiple individuals with Noonan syndrome, including some de novo cases (van Trier DC et al. Int. J. Pediatr. Otorhinolaryngol., 2015 Jun;79:874-8; Pannone L et al. Hum. Mutat., 2017 Apr;38:451-459). Arginine 265 is located in the protein tyrosine phosphatase domain of the PTPN11 protein and forms ionic interaction with glutamate 76 in the SRC-2 homology 2 (N-SH2) domain (Darian E et al. Proteins, 2011 May;79:1573-88; Pannone L et al. Hum. Mutat., 2017 Apr;38:451-459). Based on our internal structural analysis, this mutation disrupts the very sensitive interface between these two domains, leading to impaired inhibition (Hof P et al. Cell, 1998 Feb;92:441-50; Tartaglia M et al. Am. J. Hum. Genet., 2002 Jun;70:1555-63). A functional study also demonstrated that R265Q perturbs the autoinhibitory interaction between the two domains and enhances the function of the PTPN11 protein (Pannone L et al. Hum. Mutat., 2017 Apr;38:451-459). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. - |
