Multicenter Study of Fulminant Type 1 Diabetes in China

Summary

This study took FT1D（fulminant type 1 diabetes） as the research object, collected the cases of FT1D patients, and described the clinical characteristics of this type of disease. The HLA susceptibility genes of FT1D were identified by PCR and other techniques, taking age-sex-matched healthy subjects as controls and HLA genes as the research entry point.
