FGFR1 (P11362) variants and mutations

FGFR1 (also known as P11362) is a human protein-coding gene encoding a fibroblast growth factor receptor 1 protein. Its fibroblast-growth-factor signaling controls proliferation, differentiation, migration, and developmental patterning in many tissues. Germline pathogenic variants can cause hypogonadotropic hypogonadism or craniosynostosis syndromes, while fusions and other activating alterations drive selected cancers. This analysis covers 3,739 FGFR1 variants and mutations. Of these, 34% have computational variant effect predictions. Disease context includes hypogonadotropic hypogonadism 2 with or without anosmia, Hartsfield-Bixler-Demyer syndrome, and Pfeiffer syndrome. Example FGFR1 variants include W2*, W2C, and W2G.
