FGB (Fibrinogen beta chain) is a gene. The public catalogues list it as a drug target, and clinical evidence ties its variants to diagnosis, prognosis or drug response.
Cleaved by the protease thrombin to yield monomers which, together with fibrinogen alpha (FGA) and fibrinogen gamma (FGG), polymerise to form an insoluble fibrin matrix. Fibrin has a major function in haemostasis as one of the primary components of blood clots. In addition, functions during the early stages of wound repair to stabilise the lesion and guide cell migration during re-epithelialisation.
Open Targets scores its association with cancer at 0.66 (direct and indirect evidence; datatypes literature 0.72, affected pathway 0.97, genetic association 0.02, clinical 0.43).

No product in this corpus aims at FGB yet. Drugs bind the molecule precisely: to switch it off, flag the cell for the immune system, or deliver a payload.
Specificity not established: no corpus medicine is aimed at it and the catalogues give it only the role drug-target; HPA finds the RNA tissue enriched, which says where the protein sits but not whether the tumour differs from normal tissue. HPA FGB: RNA tissue enriched (liver 16,765 nTPM); no normal tissue stained high; highest cancer staining carcinoid (2 of 4 high). Distribution: no corpus cancer carries a prevalence row, threshold or catalogue link for it; Open Targets associates it with 0 specific cancer types at or above 0.5. (No rule of scripts/fetch-target-specificity.ts fired.)

Fibrin has a major function in haemostasis as one of the primary components of blood clots. In addition, functions during the early stages of wound repair to stabilise the lesion and guide cell migration during re-epithelialisation. Was originally thought to be essential for platelet aggregation, based on in vitro studies using anticoagulated blood. However subsequent studies have shown that it is not absolutely required for thrombus formation in vivo. Enhances expression of SELP in activated platelets. Location: Secreted (UniProt). Locus 4q31.3 (HGNC).
RNA: tissue enriched (liver 16,765 nTPM), detected in some normal tissues.
No normal tissue stained high; medium in Kidney.
RNA cancer enriched: Liver Hepatocellular Carcinoma 4,509 pTPM.
Medium only: breast cancer, cervical cancer, endometrial cancer, head and neck cancer.
