GeneDx	RCV000207503	SCV000207845	pathogenic	not provided	2019-12-16	criteria provided, single submitter	clinical testing	Published functional studies demonstrate a damaging effect caused by increased phosphorylation of ERK, suggesting an activation of the RAS/MAPK pathway (Denayer et al., 2008; Niihori et al., 2011); The majority of missense variants in this gene are considered pathogenic (Stenson et al., 2014); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Not observed in large population cohorts (Lek et al., 2016); This variant is associated with the following publications: (PMID: 17979197, 28027064, 17601930, 30055033, 24224811, 21686750, 22317973, 21850009, 23093928, 16170316, 19035362, 24803665, 27589201, 24169525, 16835863, 30762279, 30885829, 31394527, 31560489, 33482860, 33224014)

Women's Health and Genetics/Laboratory Corporation of America, LabCorp	RCV000013437	SCV000698555	pathogenic	Costello syndrome	2017-07-17	criteria provided, single submitter	clinical testing	Variant summary: The HRAS c.35G>C (p.Gly12Ala) variant involves the alteration of a conserved nucleotide. 3/3 in silico tools predict a damaging outcome for this variant (SNPsandGO not captured due to low reliability index). Functional studies showed that this variant increased RAS pathway activation in NIH 3T3 cells (Niihori_JHG_2011) and increased proliferation in Ba/F3 cells (Denayer_HM_2008). The variant of interest has not been found in a large, broad control population, ExAC in 120014 control chromosomes. This variant was reported in multiple Costello syndrome patients, including de novo occurrences (Aoki_NatGen_2005, Robbins_AJMG_2016, Niihori_JHG_2011). In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is classified as pathogenic.

Invitae	RCV000013437	SCV000956118	pathogenic	Costello syndrome	2023-04-21	criteria provided, single submitter	clinical testing	This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 12 of the HRAS protein (p.Gly12Ala). This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. This variant disrupts the p.Gly12 amino acid residue in HRAS. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 16170316, 20979192, 21834037, 21850009, 22317973, 23751039). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Experimental studies have shown that this missense change affects HRAS function (PMID: 17979197, 21850009, 24224811). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is expected to disrupt HRAS function. ClinVar contains an entry for this variant (Variation ID: 12603). This missense change has been observed in individual(s) with Costello syndrome (PMID: 16170316, 16372351, 16443854, 16835863, 17601930, 18042262, 21850009, 22420426, 28027064). In at least one individual the variant was observed to be de novo.
