RT Journal Article SR Electronic T1 The Major Genetic Determinants of HIV-1 Control Affect HLA Class I Peptide Presentation JF Science JO Science FD American Association for the Advancement of Science SP 1551 OP 1557 DO 10.1126/science.1195271 VO 330 IS 6010 A1 , YR 2010 UL http://science.sciencemag.org/content/330/6010/1551.abstract AB Infectious and inflammatory diseases have repeatedly shown strong genetic associations within the major histocompatibility complex (MHC); however, the basis for these associations remains elusive. To define host genetic effects on the outcome of a chronic viral infection, we performed genome-wide association analysis in a multiethnic cohort of HIV-1 controllers and progressors, and we analyzed the effects of individual amino acids within the classical human leukocyte antigen (HLA) proteins. We identified >300 genome-wide significant single-nucleotide polymorphisms (SNPs) within the MHC and none elsewhere. Specific amino acids in the HLA-B peptide binding groove, as well as an independent HLA-C effect, explain the SNP associations and reconcile both protective and risk HLA alleles. These results implicate the nature of the HLA–viral peptide interaction as the major factor modulating durable control of HIV infection.
