During early embryogenesis, the olfactory axons and gonadotrophin-releasing hormone(GnRH)-secreting neurons undergo dynamic processes of differentiation, migration and proliferation, regulated by a complex network of molecular and cellular mechanisms responding to various hormonal and developmental signals. Mutations in anosmin-1 and FGFR1 disrupt this pathway, causing Kallmann's syndrome(KS), a human hereditary disorder with GnRH deficiency and inability to smell. A primary n...
