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]

Gly15Gly in exon 2 of HRAS: This variant has not been previously described in th e literature and has not been identified in large population studies. However, t his variant is not expected to have clinical significance because it does not al ter an amino acid residue. In addition, this variant was identified in an unaffe cted parent of a proband. In summary, the Gly15Gly variant is likely benign. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant summary: The HRAS c.45C>T (p.Gly15Gly) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. Mutation Taster predicts a damaging outcome for this variant. 4/5 splice prediction tools via Alamut predict the variant to create a cryptic splice donor site, however these predictions have not been confirmed by functional studies. This variant is absent in 120088 control chromosomes from ExAC, however, it could still be a rare polymorphism. This is supported by its presence in a new database gnomAD at an allele frequency of 0.00001221 (3/245708 chromosomes). The variant of interest has not, to our knowledge, been reported in affected individuals via publications, nor evaluated for functional impact by in vivo/vitro studies. One internal sample carrying this variant also carries a pathogenic variant PTPN11 p.Asn308Asp, supporting a benign outcome. One clinical diagnostic laboratory has classified this variant as likely benign, citing the variant being present in their lab in an unaffected parent of a proband. Taken together, this variant is classified as Likely Benign. -
