Patients with Kallmann's syndrome show hypothalamic hypogonadism, hyposmia, and congenital mirror movements. As a correlate, a defect of gonadotropic neuron migration into the brain was recently detected. Considering abnormal outgrowth of neurons also as a possible substrate underlying mirror movements, we studied 3 patients and 2 asymptomatic female gene(More)
The olfactory system provides a unique model for developmental neurobiology. Precise targeting of axonal projections from sensory neurons located in the olfactory epithelium to specific neurons in the olfactory bulb establishes a highly refined spatial sensory map. Distinctively, this process is not restricted to embryonic stages, but continues during the(More)
Hypogonadotropic hypogonadism (HH) refers to an endocrine defect of hypothalamic origin resulting in gonadal hypoplasia and frequently associated with anosmia or severely impaired olfactory function (Kallmann's syndrome). This apparently results from a disruption in the migration of neurons from the olfactory placode to the bulb and hypothalamus early in(More)
We report the molecular characterization of a patient with Kallmann syndrome and bone anomalies bearing a balanced de novo translocation t(7;9)(p14.1;q31.3) which completely disrupts the A-kinase anchor protein 2 gene (AKAP2) on chromosome 9. In order to investigate the role of AKAP2 in the pathogenesis of the disease, we analyzed the expression of Akap2 in(More)
