SRY translocations, CNVs of FGF9, NR0B1, NR2F2, SOX3, SOX9, SOX10, and SPRY2, and sequence variants of NR5A1, NR2F2, RSPO1, SOX9, WNT4, WNT2B, and WT1 are responsible for the genetic mechanisms associated with 46,XX T/OT-DSD (62). The gene discussed is WNT2B; the disease is disorder of sexual differentiation.
