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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP6: Variant 7-122302620-C-A is Benign according to our data. Variant chr7-122302620-C-A is described in ClinVar as [Benign]. Clinvar id is 1263455.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.407 is higher than 0.05.
