In the present study, we chose to analyze only rs1799987 and no other SNP’s part of the CCR5 haplotype, because the G allele of this SNP is part of haplotype HHC for which associations with sarcoidosis were found and, in HIV, the G allele was intensively analyzed, shown to slow HIV progression, independent of other polymorphisms, like the CCR5Δ32 deletion. Here, CCR5 is linked to sarcoidosis.
