Genes affected

FEZF1 (HGNC:22788): (FEZ family zinc finger 1) This gene encodes a transcriptional repressor that belongs to the zinc finger double domain protein family. The encoded protein is thought to play a role in the embryonic migration of gonadotropin-releasing hormone neurons into the brain. Mutations in this gene are associated with hypogonadotropic hypogonadism-22 with anosmia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2014]

The c.1349C>T (p.P450L) alteration is located in exon 4 (coding exon 4) of the FEZF1 gene. This alteration results from a C to T substitution at nucleotide position 1349, causing the proline (P) at amino acid position 450 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
