is to a condition of abnormal and asymmetrical gonadal development leading to a disturbed
Sex Differentiation . A number of abnormalities have been reported in the
Karyotype , most commonly a
Mosaicism 45,X/ 46, XY. If
Turner Syndrome is defined as a condition where one sex chromosome is absent or abnormal, mixed gonadal dysgenesis may be interpreted as a specific variation of Turner’s. The phenotypical expression may be ambiguous,
Intersex , or male, or female pending the extent of the
Mosaicism .
It has been pointed out that the gonads may not be symmetrical, thus the development of the
Mullerian Duct and
Wolffian Duct may be asymmetrical, too.
Donahoe PK, Crawford JD, Hendren WH Mixed gonadal dysgenesis, pathogenesis, and management. Pediatr Surg. 1979 Jun;14(3):287-300. The presence of dysgenetic gonadal tissue and Y chromosome material, there is a high risk of the development of a
Gonadoblastoma , thus removal of the gonads is usually indicated.
