ClinGen RASopathy Variant Curation Expert Panel	RCV000013435	SCV000616364	pathogenic	Costello syndrome	2017-04-03	reviewed by expert panel	curation	The c.34G>A (p.Gly12Ser) 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 16170316, 16835863, 16443854, 16835863, 16881968, 17054105, 19669404). The p.Gly12Ser variant has been identified in >5 independent occurrences in patients with clinical features of a RASopathy (PS4; PMID: 20660566, 16372351, 16329078, 16969868, 18039947, 19371735, 19206176, 16835863). In vitro functional studies provide some evidence that the p.Gly12Ser variant may impact protein function (PS3; PMID: 17412879). Computational prediction tools and conservation analysis suggest that the p.Gly12Ser 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). 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). 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): PS2_VeryStrong, PS4, PS3, PM1, PM2, PP2, PP3.
Laboratory for Molecular Medicine,Mass General Brigham Personalized Medicine	RCV000013435	SCV000062131	pathogenic	Costello syndrome	2012-07-30	criteria provided, single submitter	clinical testing	The Gly12Ser variant in HRAS is the most common variant associated with Costello syndrome (Aoki 2005, Kerr 2006, Gripp 2006, Gori 2008, Dileone 2010, Estep 2006 , Gripp 2006, Lo 2008, Paquin 2009, Sol-Church 2009, Sol-Church 2006, van der Bu rgt 2007, van Steensel 2006, Zampino 2007, Zhang 2009). This variant has been re ported to have occurred de novo in many individuals. In summary, this variant me ets our criteria to be classified as pathogenic (http://pcpgm.partners.org/LMM).
GeneDx	RCV000081295	SCV000207842	pathogenic	not provided	2019-11-29	criteria provided, single submitter	clinical testing	Functional studies indicate that the G12S variant alters GTP and GDP dissociation rates resulting in increased active GTP-bound HRAS, which up-regulates the Ras/MAPK pathway (Wey et al. 2013); Not observed in large population cohorts (Lek et al., 2016); The majority of missense variants in this gene are considered pathogenic (Stenson et al., 2014); Classified as pathogenic by the ClinGen RASopathy Expert Panel (SCV000616364.3; Gelb et al., 2018); This variant is associated with the following publications: (PMID: 22317973, 27195699, 21850009, 24224811, 23093928, 16329078, 16170316, 19371735, 23751039, 21834037, 20979192, 27705751, 26350204, 24803665, 27589201, 25722179, 24169525, 28141901, 28027064, 16835863, 17412879, 16881968, 19669404, 30138938, 30055033, 30792901, 30050098, 25815234, 31394527, 29907801, 31560489, 31564432, 31712860, 31965297, 31795565, 32369273, 32371413, 33482860, 32681669)

ARUP Laboratories, Molecular Genetics and Genomics,ARUP Laboratories	RCV000081295	SCV000603969	pathogenic	not provided	2020-02-16	criteria provided, single submitter	clinical testing	The HRAS c.34G>A; p.Gly12Ser variant (rs104894229) is a very common pathogenic variant in patients diagnosed with Costello syndrome (Aoki 2005, Estep 2006, Gripp 2005, Kerr 2006, Niihori 2011, Zampino 2007). The glycine residues at codons 12 and 13 are frequently altered in both Costello syndrome patients (Aoki 2005, Estep 2006, Gripp 2005, Kerr 2006, Niihori 2011) and tumor samples (Aoki 2005, Estep 2006). Functional characterization of the p.Gly12Ser protein indicates increased downstream MEK signaling activity (Aoki 2005, Niihori 2011), consistent with the established disease mechanism of Costello syndrome, which has phenotypic overlap with Noonan syndrome. Based on available information, this variant is considered to be pathogenic. References: Aoki Y et al. Germline mutations in HRAS proto-oncogene cause Costello syndrome.

Victorian Clinical Genetics Services,Murdoch Childrens Research Institute	RCV000013435	SCV000680007	pathogenic	Costello syndrome	2016-12-16	criteria provided, single submitter	clinical testing	A heterozygous variant was identified in the HRAS gene, NM_176795.3(HRAS):c.34G>A and (chr11:534289). This substitution variant is predicted to create a change of a glycine to a serine at amino acid position 12, NP_001123914.1(HRAS):p.(Gly12Ser). The glycine at this position has high conservation but it is not situated in a known functional domain. In silico software predicts this variant to be disease causing. This variant has not been previously observed in our patient cohort and is not present in population databases. It has previously been observed in multiple families with Costello syndrome (Aoki et al 2005 Nat Genet, Kerr et al 2006 J Med Genet, Soi-Church et al Hum Mutat 2006 and Zampino et al 2007 Hum Mutat) and it has been classified as a common pathogenic variant. Based on current information this variant has been classified as PATHOGENIC.

Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego	RCV000013435	SCV000996166	pathogenic	Costello syndrome	2018-07-03	criteria provided, single submitter	clinical testing	This established pathogenic variant is found in approximately 80% of individuals with Costello syndrome (PMID: 16170316, 22261753, 20301680). This variant has been classified in ClinVar as pathogenic by the ClinGen Rasopathy Expert Panel and by several clinical diagnostic laboratories (variant ID: 12602). It is absent from the ExAC and gnomAD population databases and thus is presumed to be rare. Analysis of the parental samples was negative for the variant, indicating this variant likely occurred as a de novo event. Based on the available evidence, the c.34G>A (p.Gly12Ser) variant is classified as pathogenic.

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000013435	SCV001362310	pathogenic	Costello syndrome	2019-05-13	criteria provided, single submitter	clinical testing	Variant summary: HRAS c.34G>A (p.Gly12Ser) results in a non-conservative amino acid change located in the Small GTP-binding protein domain of the encoded protein sequence. Three of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 250394 control chromosomes (gnomAD). The variant, c.34G>A, has been reported in the literature in multiple individuals affected with Costello Syndrome (Aoki_2005, Kerr_2006, Gripp_2006, Niihori_2011). These data indicate that the variant is very likely to be associated with disease. At least two publication report experimental evidence evaluating an impact on protein function (Gain of function) and the effect of this variant is similar to other HRAS pathogenic variants (Paquin_2009, Niihori_2011). Eight ClinVar submissions from clinical diagnostic laboratories and one expert panel (ClinGen RASopathy) (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.

3billion	RCV000013435	SCV002058657	pathogenic	Costello syndrome	2022-01-03	criteria provided, single submitter	clinical testing	The variant has been observed in multiple (>3) similarly affected unrelated individuals(PMID: 16835863, 20660566, 19206176, 16329078, 16969868, 19371735, 18039947, 16372351, PS4_S). Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 17412879, PS3_S). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.695, 3CNET: 0.992, PP3_P). A missense variant is a common mechanism associated with Costello syndrome (PP2_P). It is not observed in the gnomAD v2.1.1 dataset (PM2_M). The variant is located in a well-established functional domain or exonic hotspot, where pathogenic variants have frequently reported (PM1_M). A different missense change at the same codon has been reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000012600, VCV000012603, VCV000012612, VCV000012613, VCV000040430, VCV000163690, VCV000180854, VCV000279921, VCV001209208, PM5_M). Same nucleotide change resulting in same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000012602, PS1_S). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline.
