The syndrome is associated with an increased risk of breast cancer, extragonadal germ cell tumor (a rare tumor), pulmonary disease, varicose veins, and osteoporosis. There is also an increased risk for autoimmune disorder such as lupus, rheumatoid arthritis, and Sjogren's syndrome.
Learning disabilities, despite normal or high IQ are common. The risk of dyslexia and attention deficient hyperactivity disorder may also be higher. Psychological problems like depression are associated with sex-linked disorders.
Taurodontism, an enlargement of the pulp of the teeth with surface thinning, is very common in Klinefelter syndrome. It can be diagnosed by dental x-rays.
