TL;DRAbstract

In order to investigate the diversity of ABO and Rh blood group genes in the Saudi Arabian population, we assembled the phenotypic data of approximately 66,000 subjects from ten representative Saudi populations: Al-Khobar, Riyadh, Tabuk/Madina Al-Munawaara, Jeddah, Abha, South region, Sakaka, Domah, Al-Qurayat, and Sweer. The frequencies of p[A], q[B], and r[O] alleles at the ABO locus were observed to be 0.1688, 0.1242, and 0.7070, respectively, and the frequency of the D allele at the Rh locus was 0.7138. The heterozygosities at the ABO and Rh loci were 0.4563 and 0.4086, respectively, while the combined heterozygosity was 0.4324. Homogeneity tests revealed the population of Abha to be the most heterogeneous while that of Tabuk/Madina was found to be the least heterogeneous. Homogeneity was higher among the Northern populations while Southern populations demonstrated subdivisions and stratification. Gene diversity analyses yielded a total heterozygosity value of 0.4449.
