Congenital Contractural Arachnodactyly

Congenital contractural arachnodactyly is a genetic disorder that shows itself in many areas of the body. Individuals with this condition usually have long limbs and long and slender fingers and toes. Sometimes their joints are permanently bent (contractures), making the movement of major joints difficult.

The muscles are usually underdeveloped and kyphoscoliosis (a rounded, curved back) and pectus carinatum (a protruding chest) are also present.

Heart defects may also occur, such as aortic root dilatation and mitral valve prolapse.

Unless the case is severe, life expectancy is usually normal.
