IthaID: 390
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | Pathogenic / Likely Pathogenic |
|---|---|---|---|
| Common Name: | CD 93-99 (+21 bp) | HGVS Name: | HBA1:c.280_300ins21 |
| Hb Name: | N/A | Protein Info: | N/A |
Also known as:
Comments: Found in an Iranian family both as a heterozygote (father) and compound heterozygote with -α3.7 deletion (proband and his sister). The proband was investigated for chronic hypochromic microcytic anaemia. No abnormal haemoglobin molecules were detected, hence unstable variant.
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.
