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.1220A>G (p.K407R) alteration is located in exon 4 (coding exon 4) of the FEZF1 gene. This alteration results from a A to G substitution at nucleotide position 1220, causing the lysine (K) at amino acid position 407 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
