PG - 15-21 AB - Sarcoidosis likely results from an interplay of environmental and genetic factors. Despite a recent large multicenter study, A Case-Control Etiologic Study of Sarcoidosis (ACCESS), no single causative environmental agent has been identified. Family clustering and differences in racial incidence of sarcoidosis support an inherited susceptibility to sarcoidosis. Siblings of patients with sarcoidosis have about a fivefold increased risk of developing sarcoidosis. Certain human leukocyte antigen (HLA) alleles have been consistently associated with sarcoidosis susceptibility. Furthermore, HLA-DRB1*0301/DQB1*0201 has been associated with good prognosis in Lofgren's syndrome. Many candidate genes studied based on their potential function in immunopathogenesis have been evaluated in case-control studies, but few have been consistently associated with sarcoidosis across populations. Two genome scans have been reported in sarcoidosis. One in African Americans reporting linkage to chromosome 5 and the other in German families reporting linkage to chromosome 6. Follow-up studies on chromosome 6 identified the BTNL2 gene, a B7 family costimulatory molecule to be associated with sarcoidosis. Advances in genotyping and statistical analysis are helping to elucidate the genetics of sarcoidosis.
