Brachydactyly Type D
Brachydactyly Type D (pronounced: brak-ee-dak-til-ee type dee), also known as BDD or clubbed thumb, is a genetic condition characterized by short, broad thumbs and big toes. The term "brachydactyly" comes from the Greek words "brachy" meaning short, and "dactylos" meaning finger.
Causes
Brachydactyly Type D is caused by a genetic mutation. It is an autosomal dominant trait, which means that an individual only needs to inherit one copy of the mutated gene from either parent to develop the condition. The specific gene associated with BDD is not yet known.
Symptoms
The primary symptom of Brachydactyly Type D is a short, broad thumb or big toe. The affected digit may also be bent at the joint. This condition does not typically cause any pain or functional problems.
Diagnosis
Diagnosis of Brachydactyly Type D is typically made based on a physical examination. In some cases, X-rays may be used to confirm the diagnosis.
Treatment
There is no specific treatment for Brachydactyly Type D. Treatment is typically focused on managing any functional problems that may occur as a result of the condition. In some cases, surgery may be recommended to improve the appearance or function of the affected digit.
