    Department of Medical Genetics, 8-42 Medical Science Building, University of Alberta, Edmonton, Alberta, Canada T6G 2H7
    Obes Res 13:1841-2. 2005
    ..Although no mutations likely to affect gene function were identified, we identified three variant alleles. We conclude that severe childhood-onset obesity is not commonly caused by MAGEL2 mutations...
  64. ncbi Molecular genetic analysis of normosmic hypogonadotropic hypogonadism in a Turkish population: identification and detailed functional characterization of a novel mutation in the gonadotropin-releasing hormone receptor gene

    Division of Paediatric Endocrinology and Metabolism, Cukurova University, Faculty of Medicine, Adana, Turkey
    Neuroendocrinology 84:301-8. 2006
    ..Currently known mutations account for less than 15% of cases with normosmic hypogonadotropic hypogonadism (nIHH). The objective of the study was to identify novel hereditary associations in the pathogenesis of nIHH...
