Camptodactyly is a medical condition involving fixed flexion deformity of the proximal interphalangeal joints. This involves permanent flexure of one or more phalanges (fingers) and the fifth finger is always affected. Camptodactyly is an autosomal dominant trait that is known for its incomplete expressivity as it can occur in both hands one or neither. A linkage scan proposed that the chromosomal locus of camptodactyly was 3q11.2-q13.12.
