| Gonadal Dysgenesis, Mixed Mixed Gonadal Dysgenesis A type of defective gonadal development in patients with a wide spectrum of chomosomal mosaic variants. Their karyotypes are of partial sex chromosome monosomy resulting from an absence or an abnormal second sex chromosome (X or Y). Karyotypes include 45,X/46,XX; 45,X/46,XX/47,XXX; 46,XXp-; 45,X/46,XY; 45,X/47,XYY; 46,XYpi; etc. The spectrum of phenotypes may range from phenotypic female through pseudohermaphrodite to phenotypic male, depending on the ratio in each gonad of 45,X primordial germ cells to those with normal 46,XX or 46,XY constitution. |
