Kallmann Syndrome
-genetic disorder causing hypogonadotrophic hypogonaidism, occurs in males and females but males>. causes reduced GnRH
Presentation of Kallmann Syndrome
-absent or delayed puberty, lack of sense of smell, can have hearing loss and a cleft palate
Management of Kallmann Syndrome
testosterone replacement for males, oestrogen and progesterone for females, GnRH injections and HCG injections
What is Kallmann syndrome?
Kallmann syndrome is a rare genetic condition characterized by hypogonadotropic hypogonadism (delayed or absent puberty due to low levels of gonadotropins) and anosmia (reduced or absent sense of smell).
What causes Kallmann syndrome?
Kallmann syndrome is caused by a failure of GnRH neurons to migrate from the olfactory placode to the hypothalamus during embryonic development. This is often associated with genetic mutations affecting genes such as KAL1, FGFR1, or others.
What is the inheritance pattern of Kallmann syndrome?
Kallmann syndrome can follow X-linked, autosomal dominant, or autosomal recessive inheritance patterns, depending on the genetic mutation involved.
What are the primary clinical features of Kallmann syndrome?
Delayed or absent puberty (hypogonadotropic hypogonadism)
Anosmia or hyposmia (absent or reduced sense of smell)
Additional features: cryptorchidism, micropenis, cleft palate, unilateral renal agenesis, and hearing loss.
