As the name suggests this syndrome was discovered by Dr. Klinefelter. This disease is genetic, the source of it being an extra x chromosome in males. The most common combination being xxy. the body system affected is primarily reproductive(this includes hormones). The symptoms and signs of the disease vary but typically are: not producing as much testosterone, reduced body hair, delayed puberty that might be cut short, breast enlargement, infertility, cryptorchidism, on the taller side, increased chance of breast cancer, often as children have mental disabilities, and 95-99 percent of men with the disease are infertile. ("Klinefelter syndrome" nih.gov) ("Klinefelter syndrome" medicinenet.gov)
This syndrome occurs to 1 out of every 500-1000 new born males. There is no race that is more affected by this disease. It effects only men as you have to have a y chromosome. The disease is diagnosed by it's symptoms but is under diagnosed because some have little symptoms and these symptoms overlap with those of other illnesses. Being a disease that purely has to do with chromosomal number it can not be treated, but the individual symptoms can be treated.
The prognosis of a man with klinefelter's disease is that he will most likely live a long life but what ever symptoms he does have will continue and might have more as time goes on.
