Abstract
Sex determination is the process by which an initial bipotential gonad adopts either a testicular or ovarian cell fate. The inability to properly complete this process leads to a group of developmental disorders classified as disorders of sex development (DSD). To date, dozens of genes were shown to play roles in mammalian sex determination, and mutations in these genes can cause DSD in humans or gonadal sex reversal/dysfunction in mice. However, exome sequencing currently provides genetic diagnosis for only less than half of DSD patients. This points towards a major role for the non-coding genome during sex determination. In this review, we highlight recent advances in our understanding of non-coding, cis-acting gene regulatory elements and discuss how they may control transcriptional programmes that underpin sex determination in the context of the 3-dimensional folding of chromatin. As a paradigm, we focus on the Sox9 gene, a prominent pro-male factor and one of the most extensively studied genes in gonadal cell fate determination.
期刊介绍：
Recent discoveries in experimental and clinical research have led to impressive advances in our knowledge of the genetic and environmental mechanisms governing sex determination and differentiation, their evolution as well as the mutations or endocrine and metabolic abnormalities that interfere with normal gonadal development. ‘Sexual Development’ provides a unique forum for this rapidly expanding field. Its broad scope covers all aspects of genetics, molecular biology, embryology, endocrinology, evolution and pathology of sex determination and differentiation in humans and animals. It publishes high-quality original research manuscripts, review articles, short reports, case reports and commentaries. An internationally renowned and multidisciplinary editorial team of three chief editors, ten prominent scientists serving as section editors, and a distinguished panel of editorial board members ensures fast and author-friendly editorial processing and peer reviewing.
