In the presence of anosmia, idiopathic hypogonadotropic hypogonadism has been called 'Kallmann syndrome (KS),' whereas in the presence of a normal sense of smell, it has been termed 'normosmic idiopathic hypogonadotropic hypogonadism (nIHH)' (summary by Raivio et al., 2007).

Kallmann syndrome is part of a group of conditions known as Isolated GnRH Deficiency (IGD). People with IGD have the same hormone deficiencies as Kallmann syndrome, but only individuals with Kallmann syndrome have a decreased or absent sense of smell. The genetic cause of IGD and Kallmann syndrome has been identified in about half of patients.

Its exact incidence is currently unknown, and a mutation in one of the identified KS genes has only been found in ~30% of the patients. Herein, we investigated epidemiological, clinical, and genetic features of KS in Finland. Kallmann syndrome and normosmic idiopathic hypogonadotropic hypogonadism are genetic conditions. They are caused by mutations in any of several different genes. Some, but not all, of these have been identified and the inheritance patterns mapped.

Kallmann syndrome has 669 members. 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). Kallmann syndrome (KS), also known as hypogonadotropic hypogonadism, GeneReviews - Isolated Gonadotropin-Releasing Hormone (GnRH) Deficiency. The Invitae Isolated Gonadotropin-releasing Hormone Deficiency (IGD) Panel analyzes three genes that are associated with IGD and Kallmann syndrome, Isolated hypogonadotropic hypogonadism (IHH), also called idiopathic or congenital In Kallmann syndrome, a variable non-reproductive phenotype occurs with anosmia (loss of the sense of smell) including "Isolated Gonadotropin Kallmann Syndrome and Hypogonadotropic Hypogonadism.

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. 47 rows 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.

The genetic cause of the syndrome can currently be found in 30–40 % of patients , but was not detected in our patient. Kallmann syndrome is an inherited disorder characterized by delayed or absent puberty and an impaired sense of smell. Learn more about the symptoms, causes, Kallmann syndrome results from a failure of GnRH cells to migrate to the forebrain, a phenomenon associated with mutations in the genes KAL1, FGFR1, FGF8, PROKR2, and PROK2.

The main symptom of Kallmann syndrome or nIHH is delayed or incomplete puberty. In Kallmann syndrome, this is paired with an impaired sense of smell, a condition present from birth but often not brought to a doctor’s attention until asked about it in the course of diagnosing the cause of delayed puberty.

It is the most common female chromosomal abnormality, occurring in approximately 1 in 1,000 female births.

Kallmann syndrome has 669 members. 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).

About 30 CHD7 pathogenic variants have been reported in patients with Kallmann syndrome; they account for ~ 11% of patients with a clinical diagnosis (Marcos et al. 2014).

A closely related disorder, normosmic idiopathic hypogonadotropic hypogonadism (nIHH), refers to patients with pubertal failure but with a normal sense of smell.
