This study sought to determine the potential role of HBB haplotypes for the prediction of beta-thalassemia in the Malaysian population. A total of 543 archived samples were reviewed and selected for this study. Five tagging SNPs in the beta-globin gene (HBB; NG_000007.3) were recorded and analysed for SNP-based and haplotype association using SHEsis online software. Single-SNP-based association analysis showed three tagging SNPs have statistical significant association with beta-thalassemia; IVS2-16G>C (p=0.036), IVS2-666C>T (p=0.032) and 3’UTR +314G>A (p=0.004). However, two tagging SNPs assigned as IVS2-74T>G and 3’UTR +233G>C did not yield significant association with p-value 0.099 and 0.211, respectively. In a further investigation, combined five tagging SNPs for haplotype association analysis revealed three susceptible haplotypes with significant p-values of which, assigned as haplotypes 1-2-2-1-1 (p=6.49x10-7, OR=10.371 [3.345~32.148]), 1-2-1-1-1 (p= 0.009, OR=1.423 [1.095~1.850] and 1-1-1-1-1 (p=1.39x10-4, OR=10.221 [2.345~44.555]). Another three haplotypes were found to be protective haplotype with significant p-value of which assigned as haplotypes 2-2-1-1-1 (p=0.006, OR=0.668 [0.500~0.893]), 1-1-2-2-1 (p=0.013, OR=0.357 [0.153~0.830]) and 1-1-2-1-1 (p=0.033, OR=0.745 [0.567~0.977]). This study has identified the potential use of intragenic polymorphic markers in the HBB gene, which were significantly associated with beta-thalassemia. A combination of these five tagging SNPs defined a new haplotype model for beta-thalassemia and further evaluation for the prediction of severity in beta-thalassemia.
