Triosephosphate isomerase deficiency(TPI DF)is a severe multisystem degenerative disease,manifested clinically as hemolytic anemia,neuromuscular abnormalities,and susceptibility to infection,frequently leading to death within 5 years of onset.There is a lack of effective clinical treatment as the pathogenesis underlying TPI DF remains largely unknown.In this study,we generate a transgenic zebrafish line[Tg(Ubi:TPI1E105D-eGFP)]with the human TPI1E105D(hTPI1E105D)mutation,which is the most recurrent mutation in TPI DF patients.Overexpression of hTPI1E105D affects the development of erythroid and myeloid cells and leads to impaired neural and muscular development.In conclusion,we create a TPI DF zebrafish model to recapitulate the majority clinical features of TPI DF patients,providing a new animal model for pathogenesis study and drug screening of TPI DF.
