My father has a rare type of sickle cell that affects his wbc's instead of rbc's. is there any information on this type of sickle cell trait?

Contradiction in: terms. WBCs do not have sickle cell disorder. Sickle cell disorder is due to a variant hemoglobin and only RBCs have hemoglobin in any quantity to undergo sickling.

Get better info: Your dad may have a white cell disorder but it has nothing to do with sickle cell trait which is a specific red cell disorder. You need to consult with your day and find out the proper name for his disorder before we can comment. A doc may have compared it to sickle cell trait to try to explain it.
