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]
FEZF1-AS1 (HGNC:41001): (FEZF1 antisense RNA 1)

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.453C>G (p.H151Q) alteration is located in exon 1 (coding exon 1) of the FEZF1 gene. This alteration results from a C to G substitution at nucleotide position 453, causing the histidine (H) at amino acid position 151 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
