WebDeletional HPFH and δβ-thalassemia (deletional HPFH/δβ-thalassemia) is a rare inherited condition that is characterized by increased Hb F, which results from deletions in the upstream silencer region of the γ-globin genes or upregulation of the γ-globin genes (Sankaran, Xu, & Orkin, 2010), as there is no competition from the expression of β- and …

Web11 nov. 2015 · HPFH is characterized by persistent fetal hemoglobin synthesis in adult life in the absence of major hematological abnormalities. HPFH can modify the clinical phenotype of the β- thalassemia and reduce their severity. Many forms of HPFH are considered as extremely well compensated forms of β- or δβ-thalassemia [23,24].

Web24 mrt. 2024 · Homozygotes for HPFH can express HbF in up to 100% of red blood cells (Thein and Craig, 1998). Delta-beta thalassemia is a hemoglobin disorder characterized by decreased or absent synthesis of the delta- and beta-globin chains with a compensatory increase in expression of fetal gamma-chain synthesis from the affected chromosome.
Web22 jan. 2013 · Homozygotes of HPFH are clinically normal. The normal HbA 2 levels in both parents exclude the possibility of homozygous β-thalassemia or double heterozygosity for β-thalassemia and δβ-thalassemia in the present case.
