{Reference Type}: Journal Article {Title}: GATA2 deficiency syndrome: A compensatory mechanism gone awry? {Author}: Rio-Machin A; {Journal}: Br J Haematol {Volume}: 205 {Issue}: 2 {Year}: 2024 Aug 8 {Factor}: 8.615 {DOI}: 10.1111/bjh.19638 {Abstract}: In their paper, using zebrafish models, Gioacchino et al. have demonstrated the GATA2 haploinsufficiency, the genetic hallmark of GATA2 deficiency syndrome, promotes erythroid and myeloid cytopenia, and have discovered a self-regulatory mechanism to compensate GATA2 levels and protein function. Commentary on: Gioacchino et al. GATA2 heterozygosity causes an epigenetic feedback mechanism resulting in myeloid and erythroid dysplasia. Br J Haematol 2024;205:580-593.
