Fascinating Stuff

A friend had sent me this. I had read another article about it too. The twin with the cancer has the same genetic mutation as Catherine. It is called the TEL-AML1 translocation (it involves chromosomes 12 and 21 getting "mixed up"). 20% of kids with pre-B ALL have this translocation making it the most common one. It is also considered a favorable factor in terms of relapse rate. It doesn't guarantee that she won't relapse though which is scary.
Anyway, I always think this stuff is interesting - I hope you do too.
