## TL;DR

PDGFB (Platelet-derived growth factor subunit B) is a gene. The public catalogues list it as a drug target, a biomarker and a fusion partner, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Sarcomas and Dermatofibrosarcoma protuberans.

## Summary

Growth factor that plays an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. Potent mitogen for cells of mesenchymal origin. Required for normal proliferation and recruitment of pericytes and vascular smooth muscle cells in the central nervous system, skin, lung, heart and placenta.

CIViC holds 3 clinical evidence items and 0 assertions across 1 variant, naming Imatinib Mesylate and Sorafenib Tosylate. Open Targets scores its association with cancer at 0.72 (direct and indirect evidence; datatypes affected pathway 0.61, literature 0.97, genetic association 0.20, somatic mutation 0.97, animal model 0.47).

## Fields

- Kind: Target
- Last checked: 2026-09-23
- Also known as: platelet derived growth factor subunit B; Platelet-derived growth factor subunit B
- Tags: cancer-genes-wave

- Biology: Growth factor that plays an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. Potent mitogen for cells of mesenchymal origin. Required for normal proliferation and recruitment of pericytes and vascular smooth muscle cells in the central nervous system, skin, lung, heart and placenta. Required for normal blood vessel development, and for normal development of kidney glomeruli. Plays an important role in wound healing. Signalling is modulated by the formation of heterodimers with PDGFA. Location: Secreted (UniProt). Locus 22q13.1 (HGNC).
- Where found: Sarcomas: Open Targets association 0.63 with sarcoma (MONDO_0005089); Dermatofibrosarcoma protuberans: CIViC evidence names this disease

## Notes

- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: CIViC lists 2 therapies; CIViC holds 3 clinical evidence items on its variants; UniProt disease notes describe a translocation or gene fusion involving the gene. Evidence tier "clinical-evidence" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
