Connective Tissue Disease (not Marfan)

I am 29 years old and have had several echos... I have aortic valve regurgitation, tricuspid valve regurgitation and mitral valve regurgitation. I also have a dilated aortic root. Other things to note is i am 5'7", 100 lbs, very tiny wrists, very flexible, high mouth palette, nearsighted (since elementary school), migraines, and always cold.

I had the marfan genetic blood test and it came back negative. We know there are other connective tissue disorders out there... marfan is the only one i have tested for. My cardiologist is at this point assuming i have a connective tissue disease and is not really further into a diagnosis as he says there are many many diseases out there. Is there any benefit to going to a genetic doctor and getting a proper diagnosis? If he is treating me like I have one already and watching for whatever it may cause cardiovascularly is that sufficient?

The only thing that makes me want a diagnosis is that I have 2 daughters and wish to know the odds that I have passed on this issue to one of them.

Thanks in advance!
