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.Glu139Asp (c.417G>T) variant in PTPN11 has been identified in 3 individua ls with Noonan syndrome (Tartaglia 2002, LMM unpublished data). It has not been identified in large population studies. In addition, another nucleotide change (c.417G>C) that results in the same amino acid change has also been reported in at least 10 individuals with Noonan syndrome, 1 individual with Noonan syndrome and acute lymphoblastic leukemia (ALL), 1 individual with Juvenile myelomonocyti c leukemia (JMML), and 1 individual with Noonan syndrome that developed ALL and JMML (Musante 2002, Loh 2004, Bertola 2006, Chan 2006, Hung 2007, Karow 2007, Ko 2008, Derbent 2010, Jongmans 2011, Pauli 2012, Timeus 2013). This variant has b een reported to show both familial segregation and to have occurred de novo (Jon gmans 2005, Houweling 2010). In summary, this variant meets our criteria to be c lassified as pathogenic (http://www.partners.org/personalizedmedicine/LMM). -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Experimental studies have shown that this missense change affects PTPN11 protein function (PMID: 18372317, 23584145, 20308328). This sequence change replaces glutamic acid with aspartic acid at codon 139 of the PTPN11 protein (p.Glu139Asp). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and aspartic acid. This variant is not present in population databases (ExAC no frequency). This missense change has been observed in individual(s) with Noonan syndrome (PMID: 11992261, 16358218, 19020799, 17339163). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 40512). For these reasons, this variant has been classified as Pathogenic. -
