Pubertal induction with hCG in a patient with Kallmann syndrome secondary to novel variant in PROK2 46,XY karyotype without Y chromosome microdeletion.

Most Klinefelter Syndrome (47, XXY) is a chromosomal variation in males in which one extra X chromosome is present, resulting in a 47,XXY karyotype. The extra X chromosome typically affects physical, neurodevelopmental, behavioral, and neurocognitive functioning. In Kallmann syndrome and CHH the karyotype will be normal, with 46XY or 46 XX. This is due to the problem being at the gene level not at the chromosomal level. Kallmann syndrome 1. Chris Redford ST3 2.

HH affects the production of the hormones needed for sexual development. It is present from birth and is due to deficiency of gonadotropin-releasing hormone (GnRH). Kallmann syndrome is a condition characterized by delayed or absent puberty and an impaired sense of smell.This disorder is a form of hypogonadotropic hypogonadism, which is a condition resulting from a lack of production of certain hormones that direct sexual development. Kallmanns syndrom är en endokrin sjukdom som leder till brist på könshormoner. Den brukar därför oftast upptäckas när puberteten uteblir.

Kallmann syndrome (KS) is a form of hypogonadotropic hypogonadism (HH). Both these conditions have the primary symptom of a failure to start or a failure to finish puberty. KS is also associated with a lack of sense of smell (anosmia).

It is characterized by hypogonadotropic hypogonadism in association with anosmia ot hyposmia, both of which occur as a result of impairment of olfactory axon development Kallmann syndrome is a rare genetic disorder marked by hypogonadotropic hypogonadism (HH) and anosmia, affecting 1 in 50,000 females. It is due to a defect of gonadotropin-releasing hormone (GnRH)-secreting neurons migration from the nasal olfactory epithelium to the basal hypothalamus. Kallmann syndrome is a rare genetic disorder characterized by hypogonadotropic hypogonadism associated with anosmia or hyposmia. When anosmia is absent, a similar syndrome is referred to as normosmic idiopathic hypogonadotropic hypogonadism. A genetically heterogeneous disorder caused by hypothalamic GNRH deficiency and OLFACTORY NERVE defects.
