Names and Sequences
| Functionality: | Globin gene causative mutation | Pathogenicity: | N/A |
|---|---|---|---|
| Common Name: | Gγ-Atlanta HPFH | HGVS Name: | N/A |
| Hb Name: | N/A | Protein Info: | N/A |
Also known as: Atlanta type of HPFH, Atlanta non-deletional HPFH
Comments: The Atlanta type of HPFH is characterized by a mild elevation of HbF (2-5% in heterozygotes), which is nearly all of the Gγ globin chains (>90%). It is associated with a chromosome carrying a Gγ-Gγ-globin gene arrangement [IthaID: 3596] with a nt T at position -158 [IthaID: 2127] of the two Gγ globin genes. Children carrying the Atlanta type of HPFH chromosome exhibit higher levels of HbF (3-10 years; average 8.8%). Also reported in a compound heterozygous state with HbS, presenting with microcytosis, hypochromia, and elevated HbF (9-15 years; average 5.8%).
We follow the HGVS sequence variant nomenclature and IUPAC standards.
