It is possible that the main title of the report Holt Oram Syndrome is not the name you expected.
Holt-Oram syndrome is a disorder that affects approximately 1 in 100,000 individuals. It is characterized by abnormalities in the bones of the upper limb, a family or personal history of a congenital heart malformation, and/or an abnormality in the electrical impulses that coordinate the muscle contractions 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. While this mutation can be inherited, most cases result from a new mutation in patients without a family history of the disorder.
