KLF1 drives the expression of fetal hemoglobin in British HPFH

Abstract excerpt

expression. Through a combination of in vitro and in vivo studies, we demonstrate that the mutation creates a de novo binding site for the important erythroid gene activator Krüppel-like factor 1 (KLF1/erythroid KLF). Our results indicate that introducing this single naturally occurring mutation leads to significantly boosted HbF levels.
