Holt-Oram syndrome is a disorder that affects bones in the arms and hands (the upper limbs) and may also cause heart problems. All people with this disorder have at least one limb abnormality that affects bones in the wrist (carpal bones). Often, these wrist bone abnormalities can be detected only by X-ray. Affected individuals may have additional bone abnormalities that can include a missing thumb or a thumb that looks like a finger, partial or complete absence of bones in the forearm, an underdeveloped bone of the upper arm, and abnormalities that affect the collar bone and shoulder blades. Bone abnormalities may affect each arm differently, and the left side can be affected more than the right side. In some cases, only one arm and/or hand is affected. less
