It is present from birth and is due to deficiency of gonadotropin-releasing hormone (GnRH). KS is often diagnosed at puberty due to lack of sexual development. The Genetic Testing Registry (GTR) provides a central location for voluntary submission of genetic test information by providers. The scope includes the test's purpose, methodology, validity, evidence of the test's usefulness, and laboratory contacts and credentials. Kallmann syndrome (KS) is typically characterized by hypogonadotropic hypogonadism and anosmia. The presence of a defective sense of smell, whether partial (hyposmia) or complete (anosmia) distinguishes KS from normosmic idiopathic hypogonadotropic hypogonadism with a normal sense of smell (nIHH), which can be associated with mutations in the GnRHR and GPR54 genes. Congenital hypogonadotropic hypogonadism (CHH) and Kallmann syndrome (KS) are a group of rare disorders responsible for complete or partial pubertal failure due to lack or insufficient secretion of the pituitary gonadotropins LH and FSH. The underlying neuroendocrine abnormalities are classically di ….

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. Kallmann syndrome (KS) is a condition that causes hypogonadotropic hypogonadism (HH) and an impaired sense of smell. 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). KS is often diagnosed at puberty due to lack of sexual development. Type 2 Kallmann syndrome (KAL2) is caused by mutation in the autosomal FGFR1 gene, a gene also responsible for several skeletal disorders including cleft lip and palate.

Kallmann syndrome genereviews

Kallmann syndrome (KS) is a rare genetic disorder in humans that is defined by a delay/absence of signs of puberty along with an absent/impaired sense of smell. A closely related disorder, normosmic idiopathic hypogonadotropic hypogonadism (nIHH), refers to patients with pubertal failure but with a normal sense of smell.

Kallmann syndrome (KS) is a genetically heterogeneous syndrome caused by mutations in several different loci and is characterized by hypogonadotropic hypogonadism and anosmia. Two loci have been mapped and include an X-linked (KAL1; OMIM 308700) and autosomal ( KAL2; OMIM 147950) form. GeneReviews® [Internet]. Seattle (WA): University of Washington, Seattle; 1993-2020.
