GeneDx RCV000033461 SCV000057366 pathogenic not provided 2021-10-08 criteria provided, single submitter clinical testing Reported in unrelated individuals with JMML in published literature (Loh et al., 2004; Kratz et al., 2005); Not observed in large population cohorts (Lek et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; The majority of missense variants in this gene are considered pathogenic (Stenson et al., 2014); This variant is associated with the following publications: (PMID: 21407260, 16643459, 17020470, 24803665, 29493581, 16053901, 9491886, 11992261, 8328949, 24039098, 18562489, 16263833, 14644997, 18328949, 27521173, 17053061, 26817465, 17546245, 30417923, 28607217, 28328117, 26918529, 31560489, 32164556, 15928039)
Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000037631 SCV000061293 pathogenic Noonan syndrome 2015-07-09 criteria provided, single submitter clinical testing The p.Gly60Ala variant has been reported in >20 individuals with clinical featur es of Noonan syndrome (Tartaglia 2002, Binder 2005, Bertola 2006, Limal 2006, Ta rtaglia 2006, Roti 2006, Mutesa 2008, Noordam 2008, Jongmans 2011, Ross 2014, LM M unpublished data) but not identified in large population studies. This variant occurred de novo in at least one of the affected individuals (Roti 2006). In ad dition, this variant has been reported in two individuals with clinical features of Noonan syndrome and a central nervous system tumor (neuroblastoma, Mutesa 20 08; dysembryoplastic neuroepithelia tumor, Jongmans 2011) and as a somatic chang e in AML (Loh 2004). In summary, this variant meets our criteria to be classifie d as pathogenic for Noonan syndrome in an autosomal dominant manner based on its frequency in affected individuals, de novo occurrence, and absence from control s.

Invitae RCV000459297 SCV000549986 pathogenic Rasopathy 2020-10-25 criteria provided, single submitter clinical testing This sequence change replaces glycine with alanine at codon 60 of the PTPN11 protein (p.Gly60Ala). The glycine residue is moderately conserved and there is a small physicochemical difference between glycine and alanine. This variant is not present in population databases (ExAC no frequency). This variant has been reported in multiple individuals with Noonan syndrome (NS) (PMID: 11992261, 24039098, 17020470, 26817465, 18328949). In one individual with NS and acute lymphoblastic leukemia, it was reported to be de novo (not present in either parent) (PMID: 16643459). ClinVar contains an entry for this variant (Variation ID: 40493). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: Tolerated; PolyPhen-2: Probably Damaging; Align-GVGD: Class C0). For these reasons, this variant has been classified as Pathogenic.
