There are tons of genes being discovered that are related to crohns (UC as well), on April 12, 2004 Dr. Kathryin Siminovitch identified one of the genes that predisposed the development of crohn's disease. The gene is located on chromosome 5 and normally produces a proteind that sits on the cell surface and controls movement of specific substances in and out of the cell...when altered (scratched) the gene produces a protein that functions improperly, allowing toxins increased entry into the cell.
With this knowledge they are able to work on a med (possibly heading towards a cure) and develop a drug that would make this gene function normally again, but it takes time (up to 10 yrs), but thankfully with advanced technology it could take less time.
My bum is broken....there's a big crack down the middle of it! LOL :)
