IthaID: 2244
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | (αα)JM | HGVS Name: | NC_000016.10:48642_132584del |
| Hb Name: | N/A | Protein Info: | N/A |
Also known as:
Comments: The deletion spans 83.9 kb upstream of the α-globin gene locus, extending from POLR3K gene down to NPRL3 gene, including the HS-48, HS-40 and HS-33 α-globin regulatory elements. The precise breakpoints were determined through long-read sequencing. Gap-PCR and Sanger sequencing confirmed the breakpoint. Heterozygosity occurs with α-thalassemia trait, while co-inheritance with α0-thalassemia occurs with Hb Bart's hydrops fetalis.
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.
