Chimerism 46,XX/46,XY in a phenotypic female

A female patient is reported with lymphocyte chromosome chimerism (46,XX/46,XY). Her whole-body chimerism was confirmed in the ABO blood group system by the presence of two different erythrocyte populations, A1O and OO. Normal findings were recorded at physical and gynecological examination, except for mammary hypoplasia and sterility of 7 years duration, the latter complaint being the cause for genetic examination of the patient.
