Fibroblast growth factor 6 is a protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This gene displayed oncogenic transforming activity when transfected into mammalian cells.

The mouse homolog of this gene exhibits a restricted expression profile predominantly in the myogenic lineage, which suggested a role in muscle regeneration or differentiation.Marics et al. (1989) showed that the cloned normal FGF6 gene transformed mouse NIH 3T3 fibroblasts using both focus and tumorigenicity assays.
