IthaID: 1515


Names and Sequences

Functionality: Globin gene causative mutation Pathogenicity: N/A
Common Name: Turkish (δβ)0 HGVS Name: N/A
Hb Name: N/A Protein Info: N/A

Also known as: Turkish type 3 (δβ)0

Comments: The 30 kb deletion removes the δ- and β-globin genes. The 5' breakpoint is about 1.5 kb downstream of an enhancer-like sequence of the Aγ-globin gene and the 3' breakpoint is located in the L1 repeat sequence (KpnI site) 3' to the β-globin gene. The deletion is similar to that of the Indian type of (δβ)0-thal with a comparable 5' breakpoint but a 3' breakpoint which is 2.5 kb shorter.

We follow the HGVS sequence variant nomenclature and IUPAC standards.
