Does blood type affect kidney transplantation?

Yes: The vast majority of kidney transplants are done between ABO compatible donor and recipients. Some recipients have very low titers of antibodies against the ab antigens, and they can have a successful transplant if given extra immunosuppression. Remember an o donor can given to anyone and an ab recipient can accept an organ from anyone.

ABO blood type: Although ABO incompatible transplantation is done at a small number of transplant centers in the U.S., the majority of transplant programs will do transplants between ABO compatible donors and recipients. Hence, dialysis patients who are blood type O will have to wait longer for a donor kidney than other blood groups.

Yes : most centers will not perform ABO incompatible transplant and further your wait time on the transplant list is diff based on blood type. Group O is most common and most states have the longest wait times.
