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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PM1

In a strand (size 7) in uniprot entity PTN11_HUMAN there are 8 pathogenic changes around while only 0 benign (100%) in NM_002834.5

PP2

Missense variant in the PTPN11 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 131 curated pathogenic missense variants (we use a threshold of 10). The gene has 13 curated benign missense variants. Gene score misZ: 3.1293 (above the threshold of 3.09). Trascript score misZ: 4.9438 (above the threshold of 3.09). GenCC associations: The gene is linked to Noonan syndrome and Noonan-related syndrome, Noonan syndrome with multiple lentigines, metachondromatosis, Noonan syndrome 1, Noonan syndrome, cardiofaciocutaneous syndrome, LEOPARD syndrome 1, Costello syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.34330374).

BS2

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 50 of the PTPN11 protein (p.Ala50Thr). This variant is present in population databases (rs587778636, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with PTPN11-related conditions. ClinVar contains an entry for this variant (Variation ID: 135113). 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%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
