Agent Orange? Do you have Diabetes? Or do any children of Vietnam vets have diseases?

Hi, my dad is a vietnam vet and I am 41 years old. Through the years my sibilings and myself have experienced numerous health problems. Some that have passed on to our children.  My dad has just been diagnosed with Diabetes and he has a muscle disease rhabodmysosis (spelling not right)  and may have to have dialysis. My sister that is 35 has never had any hair, she doesn't have hair follicles, and her baby was born with a chromosome defect that has caused many birth defects.  A chromosome study was done and the defect was in my sister's chromosome make-up. I have a brother that commited suicide at the age of 26, he had a anxiety disorder, but was a very intelligent young man.  I have endometriosis, IBS, and I have noticed some new things lately that indicate possible parkinson's. I haven't discussed it with anyone yet, but I am a nurse and so are one of my brothers and my sister. I just feel like something from the agent orange caused problems with us because there is not any other family history of any of this before my dad. Just wondering?
