The ABO gene is at 9q34.1 (see link below, the 4th one down).
Since Dr. D will be talking about this location in his next book, it must be important.
For the heck of it I have listed genes that caught my attention that are at 9q34.1 to 9q34.3
This is my sneaky way of getting Dr. D to tell us some more before the book comes out. If he doesn't hurry up we'll already have the whole thing figured out.
