Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PP3 PP2 PS4_Moderate PS3 PM6_Strong

This summary comes from the ClinGen Evidence Repository: The c.1510A>G (p.Met504Val) variant in PTPN11 has been reported in the literature in at least 2 unconfirmed de novo occurrences in patients and 3 independent occurrences in patients with clinical features of a RASopathy (PM6_Strong, PS4; GeneDx internal data; GTR Lab ID: 26957; SCV000057454.12; PMID:15834506, 17661820, 17020470). In vitro functional studies provide some evidence that the p.Met504Val variant may impact protein function (PS3; PMID:15834506). 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). Computational prediction tools and conservation analysis suggest that the p.Met504Val variant may impact the protein (PP3). In summary, this variant meets criteria to be classified as pathogenic for RASopathies in an autosomal dominant manner.

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]
