Brief Summary: This cross-sectional study identifies two pathogenic variants in the Delta-like noncanonical notch ligand 1 ( DLK1 ) gene in a French cohort of 121 children with idiopathic central precocious puberty (CPP).DLK1 is a noncanonical ligand of the Delta Notch pathway known to be involved in adipocyte differentiation. Its hypothalamic expression suggests a potential role in coordinating reproductive and metabolic functions. Pathogenic v...

Brief Summary: This international cohort study of 404 patients identified rare likely damaging variants in the gene MECP2 in patients with central precocious puberty. Translational experiments showed that GnRH neurons in mice express Mecp2.Over the last few years, several studies have provided insight into the epigenetic regulation of the onset of puberty1-3. DNA methylation, histone post-translational modifications and non-c...
