General Discussion

Congenital contractural arachnodactyly (CCA) is an extremely rare genetic disorder characterized by a Marfan-like body habitus (tall, slender), the permanent fixation of certain joints (e.g., fingers, elbows, knees, and hips) in a flexed position (contractures); abnormally long, slender fingers and toes (arachnodactyly); permanently flexed fingers (camptodactyly); and/or abnormally shaped ears resulting in a "crumpled" appearance. In addition, affected individuals may exhibit front-to-back and side-to-side curvature of the spine (kyphoscoliosis); feet that are abnormally positioned (talipes equinovarus or clubfoot); outward displacement of the fingers (ulnar deviation of the fingers); an abnormally short neck; and/or. Rarely, affected individuals may have a slight deformity of the valve on the left side of the heart (mitral valve prolapse). CCA is inherited as an autosomal dominant trait.
