(2) Genetic counselling helps these families to reach a diagnosis at an early age and to decide about their reproductive options. Two further families were designated as having the X-linked form of KS because the affected males among these siblings displayed synkinesia with a negative family history (families III and V). Precocious puberty. Kallmann syndrome due to genetic mutations in the genes listed below are often inherited in this pattern: Finally, it can also be inherited in an autosomal recessive pattern, which means two parents (who often show no symptoms) can have a child affected by Kallmann syndrome. 10.1038/sj.ijir.3900568.

Synkinesia has been reported to be associated only with the X-linked form of KS [16]. Because this is an inherited condition, the doctor may also ask about relatives who have experienced delayed puberty or problems with fertility. Typically, those hormones drive the gonads to produce testosterone and estrogen, which, in turn, drive the development of secondary sexual characteristics (such as breast development, pubic hair growth, and facial hair growth). The KAL1 gene is expressed in the inner ear from early developmental stages suggesting that the defect underlying the hearing loss in X-linked Kallmann syndrome occurs during the organogenesis period [9]. Physical findings associated with hypogonadism include eunuchoidal skeletal proportions. Silveira L, MacColl G, Bouloux P: Hypogonadotropic Hypogonadism. If they wish to have children, both boys and girls will also Some male patients may present with microphallus and cryptorchidism during the neonatal period. Mutations of many additional genes have been implicated in the pathogenesis of Kallmann syndrome and/or hypogonadotropic hypogonadism, including the following genes: WDR11, FGF17, IL17RD, DUSP6, SPRY4, FLRT3, AXL, SOX10,SEMA3A, and HS6ST11. Olfactory MRI may be a more useful tool for the diagnosis [23]. Some, but not all, of these have been identified and the inheritance patterns mapped. She started playing soccer at age 6 and added lacrosse in elementary school. J Clin Endocrinol Metab. 99 (4):1452-60. Is Kallmann Syndrome hereditary?
