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]

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0103 - Both loss of function and gain of function are known mechanisms of disease for this gene. Metachondromatosis (MIM#156250) and Noonan syndrome with multiple lentigines have been associated with loss of function variants, whereas Noonan syndrome 1 (MIM#163950) is caused by gain of function variants (PMIDs: 11992261, 24935154, 21533187; ClinGen expert panel). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0115 - Variants in this gene are known to have variable expressivity. Noonan syndrome is known to have variable expressivity (PMID: 20301303). (I) 0200 - Variant is predicted to result in a missense amino acid change from glycine to glutamic acid. (I) 0251 - This variant is heterozygous. (I) 0302 - Variant is present in gnomAD (v3) <0.001 for a dominant condition (1 heterozygote, 0 homozygotes). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2) (1 heterozygote, 0 homozygotes). (I) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0602 - Variant is located in a hotspot region or cluster of pathogenic variants (DECIPHER).

The variant is not observed in the gnomAD v2.1.1 dataset. Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.98; 3Cnet: 0.99). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000040561). A different missense change at the same codon (p.Gly503Arg) has been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000040558, VCV000040559, VCV000571101). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

This variant disrupts the p.Gly503 amino acid residue in PTPN11. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12960218, 16358218, 18758896, 19077116, 19737548, 24754368). 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: 40561). This missense change has been observed in individual(s) with Noonan syndrome (PMID: 18678287, 26785492). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 503 of the PTPN11 protein (p.Gly503Glu). For these reasons, this variant has been classified as Pathogenic. -
