Understanding who had what helped researchers identify eight chromosomal sites they believe may harbor genes earmarked for Osteoarthritis of the hands. Researchers believe carriers may be born with defective cartilage or with slight defects in the way the joints fit together, something that could increase the risk of Arthritis. The research is in this month's issue of Arthritis and Rheumatism.
