Rs4406273

rs4406273 is located about 28Kb centromeric of HLA-C on human chromosome 6, and as tested in at least three populations (from Europe, Pakistan and Thailand) it is an almost perfect (95%-99%) proxy for the HLA-C*06:02 MHC allele associated with psoriasis. The rs4406273(A) allele is the HLA-C*06:02 surrogate.
