(重定向自Mixed gonadal dysgenesis)
45,X/46,XY mosaicism, also known as X0/XY mosaicism and Mixed gonadal dysgenesis, is a rare disorder of sex development in humans associated with sex chromosome aneuploidy and mosaicism of the Y chromosome. This is called a mosaic karyotype because, like tiles in mosaic floors or walls, there is more than one type of cell.
