Association of childhood DHEAS concentration, pubertal development and DNA methylation at puberty-related genes (2024)
Journal Article
Sudman, M., Stöger, R., Bentley, G. R., & Melamed, P. (2024). Association of childhood DHEAS concentration, pubertal development and DNA methylation at puberty-related genes. European Journal of Endocrinology, 191(6), 623-635. https://doi.org/10.1093/ejendo/lvae156

Objective
High concentrations of dehydroepiandrosterone sulfate (DHEAS) often precede premature puberty and sometimes polycystic ovary syndrome (PCOS). We hypothesized that the underlying mechanisms might involve DNA methylation. As an indicator of...
