IthaID: 4169



Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: 132 kb deletion HGVS Name: NC_000016.10:g.47840_180168del
Hb Name: N/A Protein Info: N/A
Also known as: Dongxing deletion

We follow the HGVS sequence variant nomenclature and IUPAC standards.

Comments: Identified in a 23-year-old female in compound heterozygosity with -α4.2 [IthaID: 301], leading to microcytosis and hypochromia and the presence of Hb H and Hb Bart’s. The 132 kb deletion was detected using the Copy Number Variation Sequencing (CNV-seq) and encompasses the HBA1 and HBA2 genes, resulting in a phenotypic manifestation similar to that observed in the Southeast Asian (SEA) deletion.
