Of the SCD patients with complications, those with vaso-occlusion crisis (HbSS VOC) had relatively higher levels of ICAM-1, VCAM-1 and E-Selectin at (62.42 ng/mL ± 26.09), (634.99 ng/mL ± 324.31) and (236.77 ng/mL ± 114.40) respectively; Conclusion: Although levels of adhesion molecules were high in all the SCD patients with complications, those with vaso-occlusive crisis had higher levels. The gene discussed is SELE; the disease is Schnyder corneal dystrophy.
