The theta-1 gene may be expressed very early in embryonic life, perhaps sometime before 5 weeks. Theta-1 is a member of the human alpha-globin gene cluster that involves five functional genes and two pseudogenes. The order of genes is: 5' - zeta - pseudozeta - mu - pseudoalpha-1 - alpha-2 - alpha-1 - theta-1 - 3'. Research supports a ...
The human alpha globin gene cluster is located on chromosome 16 and spans about 30 kb, including seven alpha like globin genes and pseudogenes: 5'- HBZ - HBZP1 - HBM - HBAP1 - HBA2 - HBA1 - HBQ1-3'. The HBA2 (α 2) and HBA1 (α 1) coding sequences are identical. These genes differ slightly over the 5' untranslated regions and the introns, but ...
Table 1: α represents the presence of α-globin gene and- represents the deletion of α-globin gene. [6] The chance of a fetus developing Hemoglobin Bart's hydrops fetalis is dependent upon if one or both parent carries the alpha-thalassemia trait. Due to this disease being incompatible with life, diagnosis for it is done prenatally. [7]
Alpha 1 and alpha 2 subunits are respectively coded by genes HBA1 and HBA2 close together on chromosome 16, while the beta subunit is coded by gene HBB on chromosome 11. The amino acid sequences of the globin subunits usually differ between species, with the difference growing with evolutionary distance.
Hemoglobin variants occur when there are mutations in specific genes that code for the protein chains, known as globins, which make up the hemoglobin molecule. This leads to amino acid substitutions in the hemoglobin molecule that could affect the structure, properties, and/or the stability of the hemoglobin molecule.

Mu hemoglobin is a predicted protein encoded in the HBM gene. The mRNA is expressed at moderate levels, but the protein has not been detected by mass spectrometry. [1] [2] [3] The order of genes is: 5' - zeta - pseudozeta - mu - pseudoalpha-1 - alpha-2 - alpha-1 - theta1 - 3'.
