Characterization of the two zebrafish orthologues of the KAL-1 gene underlying X chromosome-linked Kallmann syndrome
The gene underlying X chromosome-linked Kallmann syndrome, KAL-1, has been identified for several years, yet its role in development is still poorly understood. In order to take advantage of the zebrafish as a model in developmental genetics, we isolated the two KAL-1 orthologues, kal1.1 and kal1.2, in this species. Comparison of deduced protein sequences with the human one shows 75.5 and 66.5%...
متن کاملStudy on KAL1 Gene Mutations in Idiopathic Hypogonadotropic Hypogonadism Patients with X-Linked Recessive Inheritance
Idiopathic hypogonadotropic hypogonadism (IHH) is a condition caused by low doses of hypothalamic gonadotropin-releasing hormone (GnRH) leading to absence or incomplete sexual maturation. One of the disorders leading to IHH is Kallmann syndrome which is characterized by GnRH deficiency with anosmia or hyposmia. This disorder generally occurs as a hereditary syndrome with X-linked recessive inhe...
متن کاملSimilar interstitial deletions of the KAL-1 gene in two Brazilian families with X-linked Kallmann Syndrome
Mutations in the KAL-1 gene localized at Xp22.3 have been shown to be responsible for the X-linked Kallmann syndrome (KS), a disorder characterized by the association of hypogonadotropic hypogonadism and anosmia. In this paper, we describe the investigation of two families with X-linked KS, in which similar interstitial deletions spanning exons 5 to 10 of the KAL-1 gene were identified. The pre...
متن کامل1.4 Mb candidate gene region for X linked dyskeratosis congenita defined by combined haplotype and X chromosome inactivation analysis.
Dyskeratosis congenita (DC) is a rare inherited disorder characterised by the early onset of reticulate skin pigmentation, nail dystrophy, and mucosal leucoplakia. In over 80% of cases bone marrow failure develops and this is the main cause of early mortality. The DC1 gene responsible for the X linked form (MIM 305000) of dyskeratosis congenita has been mapped to Xq28. In order to narrow the ca...
متن کاملX-linked retinoschisis with point mutations in the XLRS1 gene.
BACKGROUND X-linked retinoschisis (XLRS) is a relatively rare vitreoretinal dystrophy that causes visual loss in young men. Recently, a gene responsible for this disease, designated XLRS1, was identified, and several deleterious gene mutations were reported. OBJECTIVE To analyze Japanese patients clinically diagnosed as having XLRS formutational changes in the XLRS1 gene. METHODS Ten patien...
