Genes affected

HRAS (HGNC:5173): (HRas proto-oncogene, GTPase) This gene belongs to the Ras oncogene family, whose members are related to the transforming genes of mammalian sarcoma retroviruses. The products encoded by these genes function in signal transduction pathways. These proteins can bind GTP and GDP, and they have intrinsic GTPase activity. This protein undergoes a continuous cycle of de- and re-palmitoylation, which regulates its rapid exchange between the plasma membrane and the Golgi apparatus. Mutations in this gene cause Costello syndrome, a disease characterized by increased growth at the prenatal stage, growth deficiency at the postnatal stage, predisposition to tumor formation, cognitive disability, skin and musculoskeletal abnormalities, distinctive facial appearance and cardiovascular abnormalities. Defects in this gene are implicated in a variety of cancers, including bladder cancer, follicular thyroid cancer, and oral squamous cell carcinoma. Multiple transcript variants, which encode different isoforms, have been identified for this gene. [provided by RefSeq, Jul 2008]

Costello syndrome

Pathogenic:4

Pathogenic, criteria provided, single submitter	clinical testing	Clinical Genetics and Genomics, Karolinska University Hospital	Jul 22, 2024	This variant was found de novo in a child with Costello syndrome. It disrupts the p.Gly12 amino acid residue in HRAS. Other variants that disrupt this residue have been determined to be pathogenic (PMID: 16170316, 20979192, 21834037, 21850009, 22317973, 23751039). Experimental studies have shown that this missense change affects HRAS function (PMID: 17979197, 21850009, 24224811). In silico prediction indicates that this missense variant is expected to disrupt HRAS function. This missense change has been observed in individuals with Costello syndrome (PMID: 16170316, 16372351, 16443854, 16835863, 17601930, 18042262, 21850009, 22420426, 28027064). For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Jul 17, 2017	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. -
Pathogenic, no assertion criteria provided	literature only	OMIM	Oct 01, 2005	- -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Apr 21, 2023	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. -
