Genes affected

NSMF (HGNC:29843): (NMDA receptor synaptonuclear signaling and neuronal migration factor) The protein encoded by this gene is involved in guidance of olfactory axon projections and migration of luteinizing hormone-releasing hormone neurons. Defects in this gene are a cause of idiopathic hypogonadotropic hypogonadism (IHH). Several transcript variants encoding different isoforms have been found for this gene.
