Brachydactyly type A7 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, a wide gap between the middle and distal phalanges, and a wide gap between the proximal and middle phalanges.

The most common symptoms of Brachydactyly type A7 are shortening of the middle phalanges of the fingers and toes, and a wide gap between the first and second phalanges. Other symptoms may include a wide gap between the second and third phalanges, a wide gap between the fourth and fifth phalanges, and a wide gap between the fifth and sixth phalanges. In some cases, the nails may be abnormally shaped or curved.

The exact cause of Brachydactyly type A7 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 A7 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.
