Results indicated that HLA-B8, -DRB1*0301, and -DQB1*0201 positive patients have a significantly higher risk of acute onset of the disease (AOD), radiological stage I erythema nodosum (EN), Löfgren's syndrome, no-medicament therapy, and pulmonary sarcoidosis.
On the other hand, the HLA-DQB1*0501-DQA1*0101-DRB1*0101-B7 haplotype showed a negative association with the disease, as similarly observed in lung sarcoidosis.
