IthaID: 4082
Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | --LAMPHUN | HGVS Name: | NC_000016.10:g.158985_186051delinsCGGGAGGGA |
| Hb Name: | N/A | Protein Info: | N/A |
| Also known as: | 27 kb deletion with 9 bp insertion (Lamphun deletion) |
We follow the
HGVS sequence variant nomenclature
and
IUPAC standards.
Comments: The Lamphun deletion spans 27 kb on the α-globin gene locus and removes both functional α-globin genes, HBA2 and HBA1, as well as HBZP1, HBM, HBAP1, and HBQ. It was identified in combination with the heterozygous -α³.⁷ deletion [IthaID: 300] in a young male with HbH disease, as well as in the heterozygous state alongside a β-globin gene 3.5 kb deletion [IthaID: 3393], with Hb of 11.6 g/dL, MCV of 70.2 fL, and MCH of 22.9 pg. The deletion was characterized using a combination of MLPA, WGS, GAP-PCR, and direct sequencing.
