|---|---|---|---|
| Common Name: | --60.2 | HGVS Name: | NC_000016.10:g.147589_207883del |

Also known as:
Comments: The deletion spans approximately 60.2 kb on the α-globin gene cluster. The 5' breakpoint is located upstream of the HBZ gene and the 3' breakpoint is within the LUC7L gene. The deletion removes the entire HBZ, HBM, HBA2, HBA1, and HBQ genes. The deletion is the result of Alu-mediated homologous recombination. The proband was heterozygous for the deletion (Hb:123 g/L, MCV: 73.1 fL, MCH: 21.9 pg, HbF: 0.2%, and HbA2: 2.6%). The 60.2 kb deletion found in compound heterozygosity with -α3.7 [IthaID: 300] in her son, leading to Hb H disease without the requirement for blood transfusions.

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.
