Etymology: Franz J. Kallmann, American psychiatrist, 1897-1965
a condition characterized by the absence of the sense of smell and longer-than-average limbs. It is caused by agenesis of the olfactory bulbs and secondary hypogonadism related to a decrease of luteinizing hormone-releasing hormone (interstitial cell-stimulating hormone).
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, in some cases, is X-linked.
