When a celebrity provides a DNA sample, it usually means he’s in trouble. But when it comes to Elijah Wood, giving up his genetic material is all for a good cause, people.com reports.

The actor is donating his DNA to DNA 11, a personalized-art company, to create artwork based on Wood’s genetic profile. The piece has been donated to an eBay auction, with the proceeds going to The Art of Elysium, a charity for children with serious medical conditions.
