My twin brother was told he has Dupuytren's disease of the hand. What are my chances of getting this same condition?

Dupuytren's disease is a condition affecting the palm of the hand. Extra connective tissue forms into bumps or nodules at the base of the fingers. The ring and index fingers are affected most often.

The exact cause is unknown. There are certain risk factors that increase a person's chances of developing this problem. Family history is one. European ethnicity is another. Smoking, liver disease, diabetes, and alcohol use also increase a person's chances of Dupuytren's.
