The association of endothelin 1 (ET-1) and endothelial constitutive nitric oxide synthase (ecNOS) gene polymorphisms (G5665T and T8002C, VNTR and T-786C respectively) with the occurrence of acute chest syndrome and painful vaso-occlusive crises was evaluated in homozygous SS children. This retrospective study reveals that ET-1 T8002 and ecNOS C-786 alleles are associated with, respectively, an increased and a decreased risk of acute chest syndrome.
