From what I have read EDS is definately genetic,, however I cant seem to find out wether HMS is also genetic. Both me and my brother are very flexible (between us we can do pretty much everything on that EDS picture thread) and I am trying top work out if HMS//EDS could be the cause.

Thanks!

HMS is genetic as well...there is a debate as to whether HMS and EDS III are the same disorder.

Thanks.... might have to look into it further.
