Comments: Found in a 29-year-old female Afghan patient with compound heterozygosity in cis with the HBA1:c184A>T,p.Lys62* [IthaID: 3334] in addition to the common deletions α4.2 and α3.7, leading to non-deletional Hb H genotype. She received regular blood transfusions since her childhood [PMID: 29739111, info only from abstract].
