Kallmann syndrome
MONDO:0018800Kallmann syndrome (KS) is a developmental genetic disorder characterized by the association of congenital hypogonadotropic hypogonadism (CHH) due to gonadotropin-releasing hormone (GnRH) deficiency, and anosmia or hyposmia (with hypoplasia or aplasia of the olfactory bulbs).
Also known as: Olfacto-genital pathological sequence, congenital hypogonadotropic hypogonadism with anosmia, hypogonadotropic hypogonadism with anosmia
