MASS syndromeType: Term
1. a syndrome closely resembling both Marfan syndrome and Barlow syndrome. However, no dislocation of the lenses or aneurysmal changes occur in the aorta, and the mitral valve prolapse is by no means invariable. At present it has been assigned no separate MIM number, but shares that of the Barlow syndrome [MIM*157700].
