RAB31-Mediated Endosomal Trafficking Is Defective in RUNX1 Haplodeficiency
Conclusions: These studies provide the first evidence that RAB31 is a direct transcriptional target of RUNX1 and a mechanism for RAB31 downregulation in RUNX1 haplodeficient patients. Downregulation of RAB31 or RUNX1 results in impaired endosomal maturation/trafficking, and this may contribute to the defective handling of α-granule proteins recognized in patients with RUNX1 mutations.DisclosuresLambert: Sysmex: Consultancy; Rigel: Consultancy; Bayer: Membership on an entity's Board of Directors or advisory committees; Educational Concepts in Medicine: Consultancy; CSL: Consultancy; Novartis: Membership on an entity's...
