Tarsal carpal coalition syndrome (TCC) is a genetic condition characterized by fusion of the bones in the wrist (carpals), ankles (tarsals), and the fingers and toes (phalanges). Other bone abnormalities in the hands and feet may be present. Symptoms of TCC may include: stiffness and progressive immobility of the hands and feet and short stature. TCC is caused by mutations in the NOG gene, and it is inherited in an autosomal dominant manner. Although there is no specific treatment or cure for TCC, there may be ways to manage the symptoms. A team of doctors or specialists is often needed to figure out the treatment options for each person.
