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.

Note:
The impact thresholds provided in this section are based on the analyses performed in Tamana et.al. For any given tool, the impact thresholds defined for the set of variants with the same effect on function as the variant examined, are preferred over those defined for the full dataset.
