ClinGen RASopathy Variant Curation Expert Panel	RCV000678903	SCV000616363	pathogenic	Noonan syndrome	2017-04-03	reviewed by expert panel	curation	The c.37G>T (p.Gly13Cys) variant in HRAS has been reported as a confirmed de novo occurrence in at least 2 patients with clinical features of a RASopathy (PS2_VeryStrong; PMID 21438134, 16329078). The p.Gly13Cys variant has been identified in at least 3 other independent occurrence in patients with clinical features of a RASopathy (PS4_Moderate; PMID: 16372351). This variant was absent from large population studies (PM2; ExAC, http://exac.broadinstitute.org). The variant is located in the HRAS 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.Gly13Cys variant may impact the protein (PP3). Furthermore, the variant is in a location that has been defined by the ClinGen RASopathy Expert Panel to be a mutational hotspot or domain of HRAS (PM1; PMID 29493581). In summary, this variant meets criteria to be classified as pathogenic for RASopathies in an autosomal dominant manner. Rasopathy-specific ACMG/AMP criteria applied (PMID: 29493581): PP2, PP3, PM1, PM2, PS4_Moderate, PS2_VeryStrong.
Laboratory for Molecular Medicine,Mass General Brigham Personalized Medicine	RCV000013440	SCV000062140	pathogenic	Costello syndrome	2010-06-29	criteria provided, single submitter	clinical testing	The Gly13Cys variant has previously been associated with the clinical features o f Costello syndrome (Estep 2006, Gripp 2006, Kratz 2007). This variant has been shown to have occurred de novo in at least one individual. In summary, this vari ant meets our criteria to be classified as pathogenic (http://pcpgm.partners.org /LMM).
GeneDx	RCV000207504	SCV000207847	pathogenic	not provided	2022-06-21	criteria provided, single submitter	clinical testing	Functional studies demonstrate that G13C alters GTP and GDP dissociation rates resulting in increased active GTP-bound HRAS, which upregulates the Ras/MAPK pathway (Wey et al., 2013); The majority of missense variants in this gene are considered pathogenic (HGMD); Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 23093928, 16372351, 24803665, 24224811, 16329078, 21438134, 19213030, 28337834, 28973083, 28371260, 16835863, 33240318, 33482860, 29493581)

Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 276492 control chromosomes (gnomAD). c.37G>T has been reported in the literature in multiple individuals affected with Noonan Syndrome and Related Conditions and occurs at a codon that is known to be associated with disease (McCormick_2013, Gripp_2011). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four ClinVar submissions from clinical diagnostic laboratories (evaluation after 2014) cites the variant as likely pathogenic/pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.
