IthaID: 2555
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | α12 | HGVS Name: | N/A |
| Hb Name: | N/A | Protein Info: | N/A |
Also known as: HBA2 gene conversion
Comments: The majority of individuals who were positive for the α12 allele had a reduction in the percentage of HbA2. The α12 allele was found in compound heterozygosity with --SEA [IthaID: 309] and Hb Quong Sze [IthaID: 408].
We follow the HGVS sequence variant nomenclature and IUPAC standards.
