  • Note: Two boys and one girl had HbSβ0 genotype. The mean ± SEM ages in years of children with HbSβ0 (n = 3) and HbSβ+ (n = 5) were 9.17 ± 2.41 and 7.85 ± 5.43, respectively (and were not significantly different). Children with HbSC genotype were younger than those with HbSS or HbSβthal (a<b; P < 0.05).
