Table 2. The prevalence of red blood cell polymorphisms.

Red Cell Polymorphisms		n (%)
Haemoglobin variants	HbAA	255 (74.7)
	HbAS	31 (9.1)
	HbAC	50 (14.7)
	HbCC	1 (0.3)
	HbSC	1 (0.3)
	HbSS	3 (0.9)
G6PD variants	Normal	276 (80.9)
	Deficient	65 (19.1)

n = total number of children, % = percentage of children.

Children with different haemoglobin types as determined by electrophoresis have been presented in terms of number (n) and percentages (%) to show their prevalence. HbAA = homozygous wild type genotype, HbAS = Heterozygote sickle cell haemoglobin, HbAC = heterozygote haemoglobin C, HbSC = heterozygote haemoglobin S and C, HbCC = homozygote haemoglobin C, HbSS = homozygote haemoglobin S. G6PD variants has been determined quantitatively using commercial kit from Randox Laboratory.
