Diagnosis of XX/XY blood cell chimerism at low percentage in horse

Disorders of sexual development (DSDs) are not uncommon in horses and cause economic loss in horse breeding. Thus it is important to develop methods for unambiguous and fast identification of affected horses shortly after birth, as well those who may propagate the condition to the next generation. Genetic causes of DSDs are multivarious and still little known, thus development of diagnostic tests requires accumulating knowledge about individual cases and their aetiologies. In particular it is necessary to perform clinical, ultrasound, surgical, histological, cytogenetic and genetic analyses with close attention in all the affected individuals.
