What is the new cardiac valvular form of eds?

Rare Autosomal Reces: A recessively inherited form of eds characterized by the changes of classic eds results from failure to synthesize pro 2 chains of type i procollagen. In addition to the usual skin and joint involvement, individuals with this form of eds appear to be at increased risk for cardiac valvular dysfunction.

Not: There are 7 forms of ehlers-danlos syndrome. None specifically affect valves. Type IV which is very rare causes fragile blood vessels which can rupture. Type iii is the commonest form and causes hypermobile joints ("double jointedness") and it is benign. My research revealed no "new valvular" form of eds.
