Brief Summary: This study examined the complex process of sex determination in mice, with a specific focus on the role of WT1 isoforms, +KTS and -KTS, during gonadal development. The study provides insights into how the balance between these isoforms impacts sexual differentiation, with broader implications for understanding gonadal dysgenesis conditions, like Frasier syndrome.While the role of the SRY gene in testicular determination i...
