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]

Submissions by phenotype

Costello syndrome Uncertain:3
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 28, 2023This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 11 of the HRAS protein (p.Ala11Thr). This variant is present in population databases (rs727504496, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with HRAS-related conditions. ClinVar contains an entry for this variant (Variation ID: 178860). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is not expected to disrupt HRAS function with a negative predictive value of 95%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMar 25, 2016Variant classified as Uncertain Significance - Favor Benign. The p.Ala11Thr vari ant in HRAS has been identified by our laboratory in 1 individual with clinical features of Noonan spectrum disorders and was inherited from a reportedly unaffe cted parent. This variant has been identified in 1/16464 of South Asian chromoso mes and 1/65720 of European chromosomes by the Exome Aggregation Consortium (ExA C, http://exac.broadinstitute.org; dbSNP rs727504496). Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summary, while the clinical significance of the p.Ala1 1Thr variant is uncertain, these data suggest that it is more likely to be benig n. -
Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 28, 2021The c.31G>A (p.A11T) alteration is located in exon 2 (coding exon 1) of the HRAS gene. This alteration results from a G to A substitution at nucleotide position 31, causing the alanine (A) at amino acid position 11 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
