Congenital contractural arachnodactyly (CCA) is a genetic disorder that is typically characterized by tall height; skinny, long limbs; long, skinny fingers and toes (arachnodactyly); multiple joint deformities present at birth (congenital contractures), usually of the elbows, knees, hips, fingers and ankles; "crumpled"-looking ears, and curvature of the spine (kyphoscoliosis). Other features might also be present and vary from person to person. CCA is caused by mutations in a gene called FBN2 gene and is inherited in an autosomal dominant pattern.[1][2] CCA shares similiar signs and symptoms to Marfan syndrome; however, Marfan syndrome is not caused by mutations in the FBN2 gene.
