Association of HLA-DRB1*15:02 and DRB5*01:02 allele with the susceptibility to systemic sclerosis in Thai patients.

A genetic study, particularly in HLA-DRs, has never been performed in Thai patients with systemic sclerosis (SSc). This study was performed to investigate the association between the HLA-DR series in Thai SSc patients. HLA-DR subtypes were determined in 50 Thai SSc patients and 99 healthy controls (HCs).
