Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 1P and 0B. PP2

This summary comes from the ClinGen Evidence Repository: The c.1232C>T (p.Thr411Met) variant PTPN11 is present in 0.003% (3/113264) non-Finnish European alleles in gnomAD. The variant is located in the PTPN11 gene, which has been defined by the ClinGen RASopathy Expert Panel as a gene with a low rate of benign missense variants and pathogenic missense variants are common (PP2; PMID:29493581). Observed cases from laboratories and publications lack sufficient clinical phenotypic information to support or refute pathogenicity (Institut Universitaire d'Hématologie internal data; Institute of Human Genetics, University Hospital Magdeburg, Germany internal data; PMID:15384080). In summary, the clinical significance of the p.Thr411Met variant is uncertain. RASopathy-specific ACMG/AMP criteria applied (PMID:29493581): PP2.

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]

This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 411 of the PTPN11 protein (p.Thr411Met). This variant is present in population databases (rs121918467, gnomAD 0.003%). This missense change has been observed in individual(s) with clinical features of Noonan syndrome (PMID: 15384080). ClinVar contains an entry for this variant (Variation ID: 13341). 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 not expected to disrupt PTPN11 protein function with a negative predictive value of 80%. 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. -

The p.T411M variant (also known as c.1232C>T), located in coding exon 11 of the PTPN11 gene, results from a C to T substitution at nucleotide position 1232. The threonine at codon 411 is replaced by methionine, an amino acid with similar properties. In one study, this alteration was detected in three individuals from one family: one who met diagnostic criteria for Noonan syndrome and two who showed some symptoms, but did not meet formal diagnostic criteria. In addition, this alteration was not detected in two unaffected individuals from the same family (Bertola DR et al. Am. J. Med. Genet. A, 2004 Nov;130A:378-83). This alteration has also been noted in a stillbirth cohort (Stanley KE et al. N Engl J Med, 2020 Sep;383:1107-1116). This amino acid position is highly 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. -
