Genes affected
PTPN11 (HGNC:9644): (protein tyrosine phosphatase non-receptor type 11) The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains two tandem Src homology-2 domains, which function as phospho-tyrosine binding domains and mediate the interaction of this PTP with its substrates. This PTP is widely expressed in most tissues and plays a regulatory role in various cell signaling events that are important for a diversity of cell functions, such as mitogenic activation, metabolic control, transcription regulation, and cell migration. Mutations in this gene are a cause of Noonan syndrome as well as acute myeloid leukemia. [provided by RefSeq, Aug 2016]

Pathogenic, criteria provided, single submitterclinical testingGeneDxJun 24, 2023In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Missense variants in this gene are often considered pathogenic (HGMD); Multiple pathogenic missense variants at this residue (p.N58D, p.N58Y, p.N58H) have been reported in association with Noonan spectrum disorders; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 34184824, 26633542, 29212898, 28911804, 30050098, 29907801, 11992261, 9491886, 16053901, 29493581, 34782754) -

Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 28, 2021The p.Asn58Lys (c.174C>A) variant in PTPN11 has been reported in at least six individuals with Noonan syndrome and segregated with disease in one affected family member (Chan 2006, Miller 2017 PMID: 29212898, Sublett 2017 PMID: 28911804, D'Amico 2021 PMID: 33811550, LMM data). It has also been reported in one individual with multiple congenital anomalies (Retterer 2015 PMID:26633542). It was absent from large population studies, but has been reported in ClinVar (Variation ID 40488). Another variant resulting in the same amino acid change (c.174C>G) and two additional variants involving this codon (p.Asn58Asp and p.Asn58His) have been identified in individuals with Noonan syndrome and are classified as pathogenic by this laboratory. In summary, this variant meets criteria to be classified as pathogenic for autosomal dominant Noonan syndrome. ACMG/AMP Criteria applied: PS1, PS4, PM5_Strong, PM2_Supporting. -
Noonan syndrome 3 Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJan 25, 2016Variant summary: Variant affects a non-conserved nucleotide and results in a replacement of a medium size and polar Asparagine (N) with a large size and basic Lysine (K). 4/4 in silico tools predict the variant to be disease causing. It is absent from the large and broad cohorts of the ExAC project while it was found in several NS patients either as a de novo or as a familiar mutation suggesting pathogenicity. Variants affecting the same amino acid, Asn58His and Asn58Asp, Asn58Tyr have been reported by our laboratory in the pathogenic spectrum suggesting the Asn58 residue to be a mutational hotspot and further supporting a casual outcome for the variant. Furthermore, clinical diagnostic centers classify variant as Pathogenic via ClinVar (without evidence to independently evaluate). Considering all evidence, the variant was classified as Pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 11, 2022For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Asn58 amino acid residue in PTPN11. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12634870, 15001945, 15956085, 16263833, 16358218, 19125092, 20954246, 21204800, 22190897, 23321623, 23624134, 23756559, 25914815). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. ClinVar contains an entry for this variant (Variation ID: 40488). A different variant (c.174C>G) giving rise to the same protein effect has been determined to be pathogenic (PMID: 12634870, 15001945, 15956085, 16263833, 16358218, 19125092, 20954246, 21204800, 22190897, 23321623, 23624134, 23756559, 25914815). This suggests that this variant is also likely to be causative of disease. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 58 of the PTPN11 protein (p.Asn58Lys). -
