Camptodactyly is a medical condition that causes one or more digits (fingers or toes) to be permanently bent. It involves fixed flexion deformity of the proximal interphalangeal joints.
Camptodactyly can be caused by a genetic disorder. In that case, it is an autosomal dominant trait that is known for its incomplete genetic expressivity. This means that when a person has the genes for it, the condition may appear in both hands, one, or neither. A linkage scan proposed that the chromosomal locus of camptodactyly was 3q11.2-q13.12.
