WebThis protein starts processes that cause a fetus to develop male gonads (testes) and prevent the development of female reproductive structures (uterus and fallopian tubes). Health Conditions Related to Genetic Changes Other Names for This Gene Additional Information & Resources References WebGonad development involves a complex genetic cascade in which several factors either promote or repress each other in order to allow an initial bipotential gonad to differentiate into a testis or ovary (Fig. 3 ). Factors involved in establishment of the bipotential gonad include WT1, LHX9, EMX2, SF-1, GATA4, and its cofactor FOG2.
