The genetic defects underlying hypogonadotrophic hypogonadism (HH) are known in approximately 50% of cases. In normosmic patients, abnormal GnRH production or action may be due to defects in regulatory factors or in the genes encoding GnRH or GnRHR. Although many gene variants have been described in GNRHR (4q13.2), the potential impact of structural alterations of the resulting mutant proteins have not been studied. In this study, we analysed the 3D-structure of the variant Gn...

Introduction: Most paediatric rare diseases have an underlying genetic cause but making a molecular diagnosis is often still a challenge. The incorporation of Next Generation Sequencing (NGS) technologies into research and clinical workflows has improved the diagnosis of these disorders.Objective: To evaluate the process of NGS implementation for the diagnosis of genetic endocrine diseases in a tertiary public paediatric...
