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. We would like to hear your feedback as we continue to refine this new version of the GARD website. Familial KS was diagnosed in 27 patients belonging to five families with the X-linked mode of inheritance and two families with the autosomal recessive mode of inheritance. However, a recent report identifying the specific gene mutated in autosomal dominant KS pointed out that synkinesia may occur in the autosomal forms of KS [17]. Cleft lip, cleft palate, or high (arched) palate has been reported in 6-22% of patients with Kallmann syndrome. (1987) caused the induction and maintenance of spermatogenesis and biologic paternity by intranasal administration of gonadotropin-releasing hormone ( 152760) in low dose. This is especially important if your child also has a history of reduced or absent smell or taste. [QxMD MEDLINE Link]. [QxMD MEDLINE Link]. Because classic Kallmann syndrome and idiopathic hypogonadotropic hypogonadism are both congenital disorders, the terms classic and congenital are used interchangeably to refer to Kallmann syndrome and idiopathic hypogonadotropic hypogonadism. It may first be suspected in infancy in males with undescended testicles or a small penis. Find resources for patients and caregivers that address the challenges of living with a rare disease.

Abstract Kallmann syndrome (KS) can be characterized as genetic disorder marked by The classic symptoms of Kallmann syndrome are delayed or absent progression to puberty and an impaired sense of smell. extra problems. A mutation in the human leptin receptor gene causes obesity and pituitary dysfunction. The presence of anosmia/hyposmia and history of delayed puberty or infertility in the family are helpful in establishing the diagnosis. Nat Genet. Kallmann syndrome is a form of a group of conditions termed hypogonadotropic hypogonadism. To distinguish it from other forms of hypogonadotropic hypogonadism, Kallmann syndrome has the additional symptom of a total lack of sense of smell (anosmia) or a reduced sense of smell. New comments cannot be posted and votes cannot be cast. It is normal for sex hormones to be Hay C, Wu F: Genetics and hypogonadotrophic hypogonadism. Waldstreicher J, Seminara SB, Jameson JL, et al. The gene responsible for the X-linked form of the disease is KAL1 gene [68], and encodes the protein anosmin that is directly responsible for the migration of GnRH neurons and the olfactory nerves from the olfactory system to the hypothalamus [5, 911]. In the two families with autosomal recessive inheritance, the probability of a non-penetrant autosomal dominant gene in either parent was considered remote because of absence of any relevant family history. Olfactory MRI revealed olfactory tract agenesis in 80% of cases for which the investigation was done in the series (19/24). 2013. Homozygous mutations in the genes encoding neurokinin B (TAC3) or its receptor (TACR3) have also been described in some patients with autosomal recessive idiopathic hypogonadotropic hypogonadism. https://profreg.medscape.com/px/getpracticeprofile.do?method=getProfessionalProfile&urlCache=aHR0cHM6Ly9lbWVkaWNpbmUubWVkc2NhcGUuY29tL2FydGljbGUvMTIyODI0LWNsaW5pY2Fs.
