Syndactyly type 4 is a very rare congenital condition (present at birth) that affects all the fingers on both hands and causes fusion of the fingers. The condition may affect the toes in addition to the fingers. The condition remains poorly described due to there being an extremely low number of recorded cases.
The condition is genetic and inherited in a dominant fashion, meaning if a single parent has the condition each child has a 50% chance of inheriting the condition. Diagnosis will be confirmed by a physician checking if there is fusion of bone as well as tissue.
Treatment is discussed on a case by case basis with a physician. If you or a family member has been diagnosed with this condition, talk to your doctor about the best treatment options and resources.
