Klinefelter's and Takayasu's syndromes in one patient--a pure coincidence?

The patient is a classical case of Klinefelter's syndrome and has, in addition, pulseless disease. In angiography, the involvement of the subclavian arteries and its main branches, consistent with Takayasu's arteritis type 1, was demonstrated. It is a pure coincidence that the patient with a 47 XXY karyotype also has an illness that affects mostly women?
