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]

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpMar 29, 2016Variant summary: This c.222C>T variant affects a non-conserved nucleotide, resulting in synonymous amino acid change. 5/5 splice-site tools via Alamut predict that this variant does not affect normal splicing. This variant was found in 8/120992 control chromosomes from the broad and large populations of ExAC at a frequency of 0.0000661, which is more than 25 times greater than the maximal expected frequency of a pathogenic allele (0.0000025) in this gene, showing that this variant is benign. One internal sample undergoing for NSRD testing also carried a pathogenic variant in PTPN11 p.Met504Val, further supporting the benign outcome. Taken together, this variant has been classified as Benign. -
