Phagocytosis of sRBC
by CR3-expressing COS-7cells as measured with percentage phagocytosis. Percentage phagocytosis, mean percentage phagocytosis/COS-7 cell. Both rare variants F941V and G1145S significantly impair phagocytosis (P = 0.006 and 0.0232, respectively). No significant difference was observed between WT and either common polymorphism M441T (P = 0.70) and A858V (P = 0.47).
