Variant summary

Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP5BS1

This summary comes from the ClinGen Evidence Repository: The c.392A>G (p.Lys131Arg) variant in the PTPN11 gene has been identified in a patient with an alternate molecular basis of disease (BP5; Laboratory for Molecular Medicine internal data; VCV000013351.2, GeneDx internal data; VCV000013351.2). The filtering allele frequency of p.Lys131Arg variant is 0.042% for East Asian alleles in the gnomAD database (14/19952 with 95% CI), which is a high enough frequency to be considered strong evidence for the variant being benign by the ClinGen RASopathy Expert Panel (BS1). 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 not met due to case level data indicative of benign). This variant was observed in a healthy adult individual who did not have clinical features of a RASopathy (BS2 not met; Université Paris Diderot internal data). The ClinGen RASopathy Expert Panel has classified the p.Lys131Arg variant as likely benign. RASopathy-specific ACMG/AMP criteria applied (PMID:29493581): BS1, BP5.

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]
