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]

The p.R152H variant (also known as c.455G>A), located in coding exon 4 of the PTPN11 gene, results from a G to A substitution at nucleotide position 455. The arginine at codon 152 is replaced by histidine, an amino acid with highly similar properties. This variant has been detected in an individual from a Noonan syndrome cohort; however, clinical details were not provided and gene analysis was limited to PTPN11 (Athota JP et al. BMC Med Genet, 2020 Mar;21:50). This variant co-occurred with a de novo TNNT2 mutation in an individual with pediatric onset dilated cardiomyopathy and dysmorphic features (Herkert JC et al. Genet Med, 2018 Nov;20:1374-1386). This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 152 of the PTPN11 protein (p.Arg152His). This variant is present in population databases (rs397507521, gnomAD 0.004%). This missense change has been observed in individual(s) with Noonan syndrome (PMID: 32164556). ClinVar contains an entry for this variant (Variation ID: 40514). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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. -
