IthaID: 3578



Names and Sequences

Functionality: Globin gene causative mutation
Common Name: 2.2 Mb deletion HGVS Name: NC_000011.10:g.4052720_6253287del
Hb Name: N/A Protein Info: N/A

Also known as:

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).
