Condition	Inheritance	Intervention Categories	Intervention/Rationale	Manifestation Categories	References
Hypogonadotropic hypogonadism 22 with or without anosmia	AR	Endocrine	In Hypogonadotropic hypogonadism, surveillance in adolescence related to sexual maturation is indicated, as is monitoring of bone mineral density in order to allow early detection and treatment of disease; In order to induce and maintain secondary sex characteristics, gradually increasing doses of gonadal steroids (females: estrogen/progestin; males: testosterone/hCG) can be beneficial; Related to fertility, endocrinologic therapy (females: recombinant hCG or pulsatile GnRH therapy; males: hCG/HMG/recombinant FSH or pulsatile GnRH therapy) may be effective, though IVF may be required	Endocrine; Neurologic	25192046

Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the FEZF1 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Transcription repressor. Involved in the axonal projection and proper termination of olfactory sensory neurons (OSN). Plays a role in rostro-caudal patterning of the diencephalon and in prethalamic formation. Expression is required in OSN to cell-autonomously regulate OSN axon projections. Regulates non-cell-autonomously the layer formation of the olfactory bulb development and the interneurons. May be required for correct rostral migration of the interneuron progenitors (By similarity). {ECO:0000250}.
• Pathway: Olfactory bulb development and olfactory learning (Consensus)
