From: Rapid and reliable detection of α-globin copy number variations by quantitative real-time PCR
Copy number variation in patients. A shows data for a patient heterozygous for the α-globin gene triplication αααanti3.7. B shows a large duplication of the complete α-globin gene cluster. C demonstrates a large deletion affecting both α-globin genes, and D shows a deletion of the HS-40 region in addition to the two α-globin genes. Control samples and non-template controls are not shown.
