Patent ID: 7947451

Claim:
A method for determining that a human has an altered risk for developing psoriasis, said method comprising: a) detecting in nucleic acid from said human the presence of at least one T allele of polymorphism rs1800925 at the nucleotide position corresponding to position 101 of SEQ ID NO:22 or the presence of at least one A allele of polymorphism rs1800925 at the nucleotide position corresponding to position 101 of the complement of SEQ ID NO:22, and correlating the presence of said T allele or said A allele with said human having a decreased risk for developing psoriasis; or b) detecting in nucleic acid from said human the presence of two C alleles of polymorphism rs1800925 at the nucleotide position corresponding to position 101 of SEQ ID NO:22 or the presence of two G alleles of polymorphism rs1800925 at the nucleotide position corresponding to position 101 of the complement of SEQ ID NO:22, and correlating the presence of said two C alleles or said two G alleles with said human having an increased risk for developing psoriasis.
