HRAS HRas proto-oncogene, GTPase

ENSG00000174775 · protein coding · Open Targets profile

Signal transducer in the Ras-MAPK signaling pathway that regulates cell proliferation and survival (PubMed:22821884). Ras proteins bind GDP/GTP and possess intrinsic GTPase activity (PubMed:12740440, PubMed:14500341, PubMed:9020151). Recognized by LZTR1 that mediates its ubiquitination by a BCR (BTB-CUL3-RBX1) E3 ubiquitin- protein ligase complex (PubMed:40934300). {ECO:0000269|PubMed:12740440, ECO:0000269|PubMed:14500341, ECO:0000269|PubMed:22821884, ECO:0000269|PubMed:40934300, ECO:0000269|PubMed:9020151}.

In 7 of 15 cancers, the evidence for HRAS comes mainly from inherited variants

Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.

Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

gnomAD loss of function constraint: o/e 0.5546799898147583 (upper bound 0.9181299805641174). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Who runs trials of these drugs

No named investigators on registry trials of HRAS's approved or late-stage drugs in the last three years.

No terminated, withdrawn or suspended trials of HRAS's drugs are registered

Paediatric incentives and obligations for HRAS's drugs

For salirasib: what EMA and FDA publish about paediatric plans, orphan status and pediatric approvals, and how many registered studies take children. Each line is a yes, no or not published fact from the record linked under it; none of it is a forecast.

Rare pediatric disease voucher. FDA, content current as of 29 Apr 2026: “As of February 3, 2026, enactment of the Consolidated Appropriations Act, 2026, the rare pediatric disease PRV program will sunset after September 30, 2029. FDA may not award any PRVs under this program after September 30, 2029.” Voucher sale prices are not shown here; they appear only as company-reported news.
