NR0B1 and disorder of sexual differentiation: Although various mutations in multiple genes, including SRY, NR5A1(SF1), WT1, SOX9, DAX1(NR0B1), DHH, WNT4, DMRT1/2, ATRX, MAMLD1, and MAP 3K1have been identified to be involved in the differentiation of the testis, the genetic cause(s)underlying~ 50% of 46,XY DSD cases are still elusive [3].
