Holt-Oram syndrome is a disorder that is characterized by abnormalities in the bones of the upper limb and a family or personal history of a congenital heart malformation or an abnormality in the electrical impulses that coordinate the muscle contraction of the heart (cardiac conduction defect). In some affected individuals, an abnormal wrist (carpal) bone is the only evidence of the disease. Seventy-five percent of those affected have a congenital heart malformation. Holt-Oram syndrome is an autosomal dominant genetic condition that is associated with an abnormality in the TBX5 gene.
