Brachydactyly type A6 is a rare genetic disorder characterized by shortening of the middle phalanges of the fingers and toes. It is caused by a mutation in the HOXD13 gene. Symptoms may include shortening of the middle phalanges of the fingers and toes, as well as a wide gap between the first and second toes.

The most common symptoms of Brachydactyly type A6 are short, stubby fingers and toes, and a shortening of the middle phalanges of the fingers and toes. Other symptoms may include a shortening of the metacarpals and metatarsals, a wide gap between the first and second toes, and a wide gap between the thumb and index finger.

The exact cause of Brachydactyly type A6 is unknown. However, it is believed to be caused by a genetic mutation that affects the development of the bones in the hands and feet. It is also thought to be inherited in an autosomal dominant pattern, meaning that only one copy of the mutated gene is needed for a person to be affected by the condition.

The treatment for Brachydactyly type A6 depends on the severity of the condition. In mild cases, no treatment may be necessary. In more severe cases, surgical options may be considered. These include bone lengthening procedures, tendon transfers, and joint fusion. In some cases, orthotic devices may be used to help improve the function of the affected hand or foot. Physical therapy may also be recommended to help improve range of motion and strength.
