Due to a production error, an incorrect supplemental figure citation appeared in the fourth sentence of the KIR polymorphism modulates NK cell effector function section. “Fig. S10” should have read “Fig. S2.” The corrected sentence appears below:

Much evidence shows that DX9 binding measures the amount of cell surface KIR3DL1 (Fig. S2 and references 25–27), so the allotypic differences observed are not the result of varying affinity for DX9.
