GeneID: 14


Common Name: α3.7 hybrid Type: Gene
Chromosome: 16 (NC_000016.10) Locus: NG_000006.1 (α-locus)
HUGO Symbol: N/A Full Name: N/A
Exons: 3 Introns: 2

The alpha-2 (HBA2) and alpha-1 (HBA1) coding sequences are identical. These genes differ slightly over the 5' untranslated region and introns, but differ significantly over the 3' untranslated region. Alpha thalassaemias result from deletions of one or both of the HBA2 and HBA1 genes; some non-deletion alpha thalassaemias have also been reported. The common α+-thalassaemia deletion “-α3.7” results from homologous recombination between misaligned chromosomes. Incorrect pairing of the HBA2 and HBA1 genes in “-α3.7” deletion leads to the production of the HBA2/HBA1 hybrid gene and a 3.7 kb deletion.
