MAMLD1 and disorder of sexual differentiation: Through NOTCH1/2, the following eight genes were shown to be associated with MAMLD1:WNT9A/9B, GLI2/3, RET, FLNA, PTPN11, and EYA1. Our findings provide further evidence that individuals with MAMLD1-related 46,XY DSD could carry two or more variants of known DSD-related genes, and the phenotypic outcome of affected individuals might be determined by multiple genes.
