Has anyone ever died from Klinefelter's Syndrome?

For a school assignment I got assigned Klinefelter's Syndrome and one of the questions is 'What is the survival rate?"
Well, I couldn't find anything like that so has anyone ever even died from it? If they have, what is the survival rate?

Outlook (Prognosis) -
Most patients have a normal, productive life.

You could say 100% in uncomplicated cases.
Complications may include-
The syndrome is associated with an increased risk of:
Breast cancer
Extragonadal germ cell tumor (a rare tumor)
Lung disease
Varicose veins
Osteoporosis
Autoimmune disorders such as lupus, rheumatoid arthritis, and Sjogren syndrome
Learning disabilities, despite normal or high IQ
Dyslexia
Attention deficient hyperactivity disorder
Depression
Taurodontism, which is when the teeth have enlarged pulp and a thinning surface, is very common in Klinefelter syndrome. It can be diagnosed by dental x-rays.
