a type of hypogonadotropic hypogonadism caused by failure of fetal gonadotropin-releasing hormone neurons to migrate to the thalamus, usually associated with anosmia or hyposmia. It is usually passed by autosomal recessive inheritance, and some cases are x-linked.

hy·po·go·nad·ism with an·os·mi·a
failure of sexual development secondary to inadequate secretion of pituitary gonadotrophins, associated with anosmia due to agenesis of the olfactory lobes of the brain. Autosomal dominant [MIM*147950], autosomal recessive [MIM*244200], and X-linked recessive [MIM*308700] forms exist; the X-linked form is caused by mutation in the Kallmann gene (KAL1) on Xp.
