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 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 Kallmann syndrome combines an impaired sense of smell with a hormonal disorder that delays or prevents puberty. The hormonal disorder is due to underdevelopment of specific neurons, or nerves, in the brain that signal the hypothalamus. Without these neurons, the hypothalamus cannot properly stimulate the production and release of certain hormones. 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's syndrome is a genetic condition in which there is a complete or incomplete loss of the sense of smell and severe hypogonadism that is associated with infertility and delayed/absent puberty. Epidemiology of Kallmann Syndrome Most cases of Kallmann's syndrome are inherited by an x-linked pattern, hence more common in men
.025% of the population. Its occurrence is more common in males than in females. It is an X-linked trait and affects the adrenal glands, which causes a deficiency of important endocrine hormonesthat are needed in order for proper sexual development to occur Kallmannův syndrom je vzácné geneticky podmíněné vrozené onemocnění.

Franz Jozef Kallmann was the first who described this disease in 1944. He suggested, that this disease has hereditary background. At present, six genes are regarded as causal genes of KS
Kallmann syndrome is a genetic disorder where there might be mutations in one or more genes such as ANOS1, CHD7, FGF8, FGFR1, PROK2, and PROKR2. From researches, it is found that the gene responsible for migration of neurons which produces gonadotropin-releasing hormone is also involved in the migration of neurons from developing nose to frontal lobe of brain Kallmann syndrome is a form of secondary hypogonadism reflecting the fact the primary cause of the defect in sex hormone production lies within the pituitary and hypothalamus rather than a physical defect of the testes or ovaries themselves. Kallmann syndrome was described in 1944 by Franz Josef Kallmann, a German-American geneticist
Kallmann's syndrome is a genetic condition in which there is a complete or incomplete loss of the sense of smell and severe hypogonadism that is associated with infertilityand delayed/absent puberty. Epidemiology of Kallmann Syndrome Most cases of Kallmann's syndrome are inherited by anx-linked pattern, hence more common in men Kallmann syndrome is named after Franz Joseph Kallmann, a German-born psychiatrist who described in 1944 twelve subjects from three families who presented with a syndrome of missed puberty, anosmia, and color blindness. Yet, several other eponyms for the same syndrome can be found in the literature Broadly speaking, products of the Kallmann syndrome genes have a role in olfactory nerve development, whereas those of pure CHH genes regulate GnRH neurosecretory function. Patients harbouring heterozygous (mono-allelic) mutations of two or more different CHH genes are increasingly being identified (oligogenic inheritance)

Kallmann syndrome: a genetic condition characterized by an absent sense of smell along with absent or delayed puberty. It is a type of hypogonadotrophic hypogonadism, a situation in which the production of hormones that control sexual development is impaired. Most affected persons do not develop secondary sexual characteristics at puberty Kallmann syndrome is a genetic condition in which the hypothalamus, a gland in the brain, does not produce certain hormones that tell the pituitary gland to release more hormones to tell the ovaries to begin puberty. FGFR1 mutations are the cause of about 10 percent of Kallman syndrome cases Kallmann syndrome is a disorder of hypogonadotropic hypogonadism, delayed puberty, and anosmia. Description Hypogonadotropic hypogonadism (HH) occurs when the body does not produce enough of two important hormones, luteinizing hormone (LH) and follicle stimulating hormone (FSH)
Kallmann syndrome (KS) is a rare genetic disorder characterized by hypogonadotropic hypogonadism associated with anosmia or hyposmia. When anosmia is absent it is simply referred to as idiopathic hypogonadotropic hypogonadism (IHH) Kallmann syndrome is one form of hypogonadotropic hypogonadism, a condition in which the body does not produce enough hormones needed for sexual development. Normally, hormones made in the hypothalamus of the brain direct the body to develop secondary sex characteristics during puberty One type of GnRH deficiency that occurs in conjunction with a lack of sense of smell, called anosmia, is known as Kallmann syndrome. GnRH (gonadotropin releasing hormone) is an essential hormone for sexual development, puberty and fertility Kallmann's syndrome. This is an abnormal development of the area of the brain that controls the secretion of pituitary hormones (hypothalamus). This abnormality can also affect the ability to smell (anosmia) and cause red-green color blindness. Pituitary disorders

Reduced hormone production by testes Other articles where Kallmann syndrome is discussed: gonadotropin-releasing hormone: This disorder is called Kallmann syndrome and is usually caused by a mutation in a gene that directs the formation of the olfactory (sense of smell) system and the formation of parts of the hypothalamus. Abnormalities in the pulsatile secretion of GnRH result in subnormal fertility and abnormal o
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 Pathophysiology of Kallmann syndrome consists of anormal migration of cells which produces luteinising hormone releasing factor (LHRH) from the olfactory plate to the hypothalamus .
