Patent ID: 7858319

Claim:
A method of treating a male Caucasian human subject in need of treatment with abacavir, comprising, (a) identifying a male Caucasian human subject in need of treatment with abacavir, who has not previously been administered abacavir; (b) performing a genotyping technique on a biological sample from said subject to determine whether the subject's HLA-B genotype includes an allele selected from the HLA-B57 allele and the HLA-B*5701 allele; (c) detecting the absence of an HLA-B57 or HLA-B*5701 allele in the subject's genotype; (d) correlating the absence of HLA-B57 or HLA-B*5701 alleles with a decreased risk of experiencing a hypersensitivity reaction to abacavir compared to the risk if an HLA-B57 or HLA-B*5701 allele were detected; and (e) administering abacavir to the subject.
