HLA-DR52
HLA-DR52 is an HLA-DR serotype that recognizes gene products of HLA-DRB3 locus. Three allele groups can produce 35 isoforms.
DRB3, DRB4, and DRB5 are minor DR beta-encoding loci, and they have been recognized as having distinct evolution, having diverged from DRB1 around 4 million years ago.
The DRB3 locus is only apparent in a small subset of DR haplotypes, and most individuals lack DRB3.
DR52 serotype is positively associated with systemic sclerosis, inflammatory myopathies, inclusion body myositis,
DRB3*01 is positively associated with sarcoidosis, Grave's Disease, pulmonary sarcoidosis,
DRB3*01:01:DRB1*03:01 is linked to Lofgren's syndrome
DRB3*02:02 is also linked to Grave's disease, serum IgG antibodies to Chlamydia pneumoniae with essential hypertension, acute necrotizing encephalopathy
DRB3*03:01 is weakly associated with anticardiolipin antibodies in SLE
