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]

Variant classified as Uncertain Significance - Favor Benign. The Tyr375Cys varia nt in PTPN11 has not previously been reported in the literature or been observed identified in our laboratory, although it is listed in dbSNP (rs41299183, not v alidated). Tyrosine (Tyr) at amino acid position 375 is not highly conserved in different species, and two different computational analyses predict this variant to have a benign effect on the function of the protein. However, in the absence of additional data, the clinical significance of this variant cannot be determi ned at this time. -

The c.1124A>G (p.Y375C) alteration is located in exon 10 (coding exon 10) of the PTPN11 gene. This alteration results from a A to G substitution at nucleotide position 1124, causing the tyrosine (Y) at amino acid position 375 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 375 of the PTPN11 protein (p.Tyr375Cys). This variant is present in population databases (rs41299183, gnomAD 0.006%). 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: 40544). 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 not expected to disrupt PTPN11 protein function with a negative 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. -
