It is caused by a mutation in a specific gene that is responsible for the development of the heart and upper limbs.
People with Holt-Oram syndrome may have various heart defects, such as a hole in the heart or an abnormal heartbeat. They may also have skeletal abnormalities in their upper limbs, such as missing or underdeveloped bones. While the syndrome is rare, it is important for those affected to receive proper medical care and support to manage their symptoms and improve their quality of life.
Causes of Holt-Oram syndrome
Holt-Oram syndrome is caused by changes in a person's genes. These changes can happen randomly when the egg and sperm come together to make a baby. Sometimes, the gene that is responsible for making a protein important for the development of the heart and upper limbs does not work properly. This can lead to the person being born with heart defects and skeletal issues in their arms and hands.
Another factor that can cause Holt-Oram syndrome is if a person inherits the changed gene from a parent who already has the syndrome. In this case, the parent may pass on the gene to their child, resulting in the syndrome being present in the family. It is important for individuals with a family history of Holt-Oram syndrome to talk to a healthcare provider about their risk of passing on the gene to their children.
Who is affected by it
