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)

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.4).
• BP6: Variant 7-122303727-C-A is Benign according to our data. Variant chr7-122303727-C-A is described in ClinVar as [Likely_benign]. Clinvar id is 1904434.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=1.49 with no splicing effect.
