|---|---|---|---|
| Common Name: | 2.2 Mb deletion | HGVS Name: | NC_000011.10:g.4052720_6253287del |

Comments: The de novo deletion was reported in a mixed European descent neonate presented with microcytic hemolytic anemia, hyperbilirubinemia, hypoglycemia and hypothermia. The propositus required two blood transfusions in the first two months of life. SNP microarray analysis identified a 2.2 Mb deletion containing 77 genes, including the entire β-globin gene cluster as well as the β-globin LCR, causing εγδβ thassaemia. The 5’ breakpoint is localised, at position 4052720 and the 3’ breakpoint is localized at position 6253287 (coordinates: GRCh38.p13, NC_000011.10).
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.
