Pathogenic, criteria provided, single submitter | clinical testing | 3billion | Oct 02, 2021 | The variant has been previously reported as de novoo in at least four similarly affected unrelated individuals (PMID: 22315187, 17020470, 11992261, 3billion dataset, PS2, PS4). Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 15987685, 18372317, 23584145, PS3). The variant was observed as assumed (i.e. paternity and maternity not confirmed) de novoo (3billion dataset, PM6). It is not observed in the gnomAD v2.1.1 dataset (PM2). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.769, 3Cnet: 0.960, PP3). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. - |

Pathogenic, criteria provided, single submitter | clinical testing | Athena Diagnostics Inc | Sep 01, 2020 | This variant occurs de novo in an individual tested at Athena Diagnostics and in published literature (PMID: 21706501). Furthermore, it has been reported in multiple unrelated symptomatic individuals (PMID: 30417923, 31560489, 28363362, 29907801, 19020799).

Missense variant in PTPN11 that has a low rate of benign missense variation and in which missense variants are a common mechanism of disease - PP2.

Pathogenic, reviewed by expert panel | curation | ClinGen RASopathy Variant Curation Expert Panel | Apr 03, 2017 | The c.417G>C (p.Glu139Asp) variant in PTPN11 has been reported as a confirmed de novo occurrence in at least 2 patients and at least 5 other independent occurrences in patients with clinical features of a RASopathy (PS2_VeryStrong; PS4; GeneDx, Baylor, BC Children's internal data; SCV000057396.11, SCV000196664.1, SCV000803709.1; GTR Lab ID: 26957, 1006, 249401 PMID: 22315187, 17020470, 11992261). This variant was absent from large population studies (PM2; ExAC, http://exac.broadinstitute.org). In vitro functional studies provide some evidence that the p.Glu139Asp variant may impact protein function (PS3; PMID: 23584145, 15987685, 18372317). 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). Computational prediction tools and conservation analysis suggest that the c.417G>C (p.Glu139Asp) variant may impact the protein (PP3). In summary, this variant meets criteria to be classified as pathogenic for RASopathies in an autosomal dominant manner. Rasopathy-specific ACMG/AMP criteria applied (PMID:29493581): PS2_VeryStrong, PS3, PS4, PM2, PP2, PP3. - |

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 25, 2022 | This sequence change replaces glutamic acid, which is acidic and polar, with aspartic acid, which is acidic and polar, at codon 139 of the PTPN11 protein (p.Glu139Asp). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with Noonan syndrome (PMID: 11992261, 17339163, 19020799, 22315187). ClinVar contains an entry for this variant (Variation ID: 40513). 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. Experimental studies have shown that this missense change affects PTPN11 function (PMID: 15987685, 18372317, 23584145, 24628801). For these reasons, this variant has been classified as Pathogenic. - |

Noonan syndrome 3 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Women's Health and Genetics/Laboratory Corporation of America, LabCorp | Aug 28, 2017 | Variant summary: The PTPN11 c.417G>C (p.Glu139Asp) variant causes a missense change involving the alteration of a conserved nucleotide located in the SH2 domain (IPR000980) (InterPro). 3/4 in silico tools predict a damaging outcome for this variant (SNPsandGO not captured due to low reliability index). Functional studies demonstrated the SHP2-D139E mutant to exhibit dramatically enhanced catalytic activation (3.5-fold), significant increase in phosphopeptide binding affinity of PTPN11, and approximately 4-fold increase in phosphatase activity after stimulation (Martinelli_2008, Tartaglia_2006). These findings from functional studies further corroborate the established molecular mechanism of disease (Gain of Function) attributed to pathogenic variants in the PTPN11 gene. The variant is absent in the control population datasets of ExAC in 121798 control chromosomes. This variant was reported in multiple patients with Noonan syndrome (Tartaglia_2006, Bertola_2006, Musante_2003). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic. - |

Cardiovascular phenotype Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 16, 2021 | The p.E139D pathogenic mutation (also known as c.417G>C) is located in coding exon 4 of the PTPN11 gene. This alteration results from a G to C substitution at nucleotide position 417. The glutamic acid at codon 139 is replaced by aspartic acid. This alteration, and another nucleotide change resulting in the same amino acid substitution (c.417G>T), have been detected in multiple individuals reported to have Noonan syndrome or suspected Noonan syndrome, having been reported as occurring de novo in at least one case (Tartaglia M et al. Am J Hum Genet. 2002;70:1555-63; Jongmans M et al. Horm Res. 2004;62 Suppl 3:56-9; Bakker M. Prenat Diagn. 2011;31:833-40; Nair S et al. Pediatr Blood Cancer. 2015;62:1084-6; Chinton J et al. Arch Argent Pediatr, 2019 10;117:330-337; Athota JP et al. BMC Med Genet, 2020 03;21:50). Some individuals with this alteration were also reported to develop leukemia (JPauli S et al. Am J Med Genet. 2012;158A:652-8; Park HD et al. Ann Hematol. 2012;91:511-7). In addition, this alteration was determined to be the result of de novo mutation or germline mosaicism through whole exome sequencing in 3 families with isolated cases of Noonan syndrome (Ambry internal data). Furthermore, a functional study found this mutation altered the binding specificity of the C-SH2 domain so that they were similar to the N-SH2 domain and increased the phosphopeptide binding affinity (Martinelli S et al. Hum Mol Genet. 2008;17(13):2018-29). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. - |
PTPN11 Related Disorders Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego | Aug 22, 2020 | This variant has been previously reported as a de novo or heterozygous change in patients with PTPN11-related disorders (PMID: 11992261, 22315187, 19020799, 17339163, 32164556, 28363362). Functional studies have reported that the variant alters the specificity of the C-SH2 domain ultimately leading to functional dysregulation and increased PTPN11 activation (PMID: 18372317, 23584145). It is absent from the gnomAD population database and thus is presumed to be rare. The c.417G>C (p.Glu139Asp) variant affects a highly conserved amino acid and is predicted by multiple in silico tools to have a deleterious effect on protein function. Analysis of the parental samples was negative for the variant, indicating this variant likely occurred as a de novo event. Based on the available evidence, the c.417G>C (p.Glu139Asp) variant is classified as Pathogenic. - |
