Alpha globin gene cluster and HS-40 region deletion and duplication mutation analysis in Blood or Tissue by Molecular genetics method
Active
Term Description
This assay detects the dosage (deletion and duplication) of alpha globin genes, including HBZ, HBM, HBA2, HBA1, HBQ1, located on the short (p) arm of chromosome 16 at position 13.3. The assay can also be used to detect the presence of deletions in the upstream LCR/HS-40 regulatory region. Deletions of the HBA1 and/or HBA2 genes are the most common cause of alpha thalassemia and in rare cases, mutations in or near these genes can also cause the disease. [GHR condition: alpha-thalassemia]
Part Description
LP343939-7 Alpha globin gene cluster & HS-40 region
The human alpha globin gene cluster located on chromosome 16 spans about 30 kb and includes seven loci: 5 '- zeta - pseudozeta - mu - pseudoalpha-1 - alpha-2 - alpha-1 - theta - 3'. The alpha-2 (HBA2) and alpha-1 (HBA1) coding sequences are identical. These genes differ slightly over the 5' untranslated regions and the introns, but they differ significantly over the 3' untranslated regions. Two alpha chains plus two beta chains constitute HbA, which in normal adult life comprises about 97% of the total hemoglobin; alpha chains combine with delta chains to constitute HbA-2, which with HbF (fetal hemoglobin) makes up the remaining 3% of adult hemoglobin. Alpha thalassemias result from deletions of each of the alpha genes as well as deletions of both HBA2 and HBA1; some nondeletion alpha thalassemias have also been reported.

- First Released
- Version 2.65
- Last Updated
- Version 2.66 (NAM)
- Change Reason
- Corrected Component from "HBA1 & HBA2 gene deletion" to accurately represent assays defined as "HBA1 & HBA2 gene deletion" but that are actually detecting deletions and duplications within the alpha globin gene cluster (16p13.3), which includes HBA1 & HBA2 genes. These assays also commonly assess deletions in the HS-40 upstream regulator element.
