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.

The c.1523G>C (p.R508P) alteration is located in exon 15 (coding exon 15) of the NSMF gene. This alteration results from a G to C substitution at nucleotide position 1523, causing the arginine (R) at amino acid position 508 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
