Abstract

To determine the mechanism for the coexistence of XX chromosomal maleness and true hermaphroditism in the same family, we performed cytogenetic and molecular genetic analyses, using DNA probes from the short arm of the Y chromosome. These studies excluded the following possible mechanisms: (1) an inherited, mitotically unstable Y chromosome that results in chromosomal mosaicism, (2) an inherited Y-to-X or Y-autosomal translocation, (3) recurrent Y-to-X translocation, and (4) incomplete inactivation of the X chromosomal homolog for the testicular determining factor. We conclude that the disorder of sexual differentiation observed in this family can be best explained by a dominant autosomal gene with variable expressivity.
