Hydralazine 118-129 complement C4A (Rodgers blood group) Homo sapiens 56-59 3873356-6 1985 We show that hydralazine binds more efficiently to the C4A than to the C4B gene product and suggest that C4 type may predispose patients to hydralazine-induced SLE. Hydralazine 13-24 complement C4A (Rodgers blood group) Homo sapiens 55-58
