Brief summary: Using a combination of expression studies in human embryos as well as functional studies in zebrafish and genetic sequencing of patient with congenital hypogonadotropic hypogonadism, this study identified a novel role for Jag1/Notch signaling in the development of GnRH neurons.GnRH neurons have a unique characteristic as they start life in the olfactory placode and then migrate into the hypothalamus during embryonic development, thanks to ...

Brief summary: The authors provide the first description of antagonistic hormone mutations as the cause of congenital disease in humans. The paper describes detailed characterizations of two novel, antagonistic leptin mutations underlying a formerly unrecognized form of congenital leptin dysfunction and delineate the challenges these mutations pose to the diagnosis and therapy of the disease.After the initial description of biologically inactive leptin v...
