The study aimed to analyze the genotype of α and β-globin in Cantonese people to enhance genetic diagnosis for thalassemia.
Various methods like PCR and DHPLC were employed to diagnose thalassemia in 454 cases from Guangdong, revealing that 438 were affected, with a majority being α-thal cases.
The findings highlighted dominant mutations in α-thal and specific genotypes for β-thal, alongside the discovery of new SNPs, establishing the effectiveness of combining DHPLC with gene sequencing in detecting thalassemia mutations.
