A paper was written about the genetics of camptodactyly in a large family from Hessen, Germany. The condition is restricted to the little (5th) fingers. Knuckle pads are present in most cases and are usually found on all fingers, except for the thumb. This is more prevalent and pronounced in women. Men are also affected but to a lesser extent.

The gene is found on chromosome three.

I found this technical article: http://www.nature.com/ejhg/journal/v.../5201957a.html

Does this describe your hands? Is this simple camptodactyly or is it part of a genetic disorder (eg. camptodactyly, tall stature, and hearing loss syndrome)?

P.S. I am also my family's amateur genealogist.
