Key Enhancer of Gene Critical for Male Sex Development Identified

An international team of researchers says they have identified a key enhancer of Sox9, a gene critical for male sex development,  and demonstrated that deleting that non-coding DNA results in male-to-female sex reversal in mice. The study ( “Sex reversal following deletion of a single distal enhancer of Sox9 ”)  published in  Science , deepens understanding of the normal process of sex determination in mammals and could also have important implications f
