title: [Host's genetics in HIV disease].
abstract: In the 1990 s, the variability of responses to human immunodeficiency virus (HIV) could only be tracked by phenotypic criteria such as the number of CD4T lymphocytes, the occurrence of opportunistic infection, the disease free survival without treatment. In 1996, the viral load is the leading phenotype for genetic studies. Ever since, thanks to a better understanding of the HIV infection pathophysiology, numerous studies helped to highlight the influence of genetic variability on inter-individual response to this virus. Among the genes having an impact, we can quote the following examples: CCR5, HLA-B and HLA-C genes. Practical applications of genetics in clinical medicine include search for HLA-B*57:01 before abacavir introduction. Recently, an eradicating treatment for HIV disease after bone marrow transplantation with a donor homozygote for a CCR5 gene non-functional variant (CCR5Δ32) has been reported. Interest in genetics of chronic viral infection is not specific to HIV. It has also been used on other viral diseases and it has gained a major place on the management of diseases.
