HIV-1 Infection Vs HIV-1 Antibody-Negative Individuals And Genotypic Markers G-Test Jacinta Gaitor 2/15/02
Rationale • Genomic DNA was screened by using 170 mapped polymorphic loci such as CD4, SCYAL, HLA-DQA1, TCRA, TCRB, and CKR5 to locate distortion of allele and geneotype frequency among HIV-1 positive vs high risked HIV-1 negative persons. • The significance of the geneotypic association between the HIV-1 positive and the high risked HIV-1 negative persons for each of the 170 loci is plotted in the following graph in physical order along each chromosome.

Conclusion • According to the data displayed in the graph, CKR5 show a significant distortion of genotype frequencies among the infected vs uninfected. • The normal or wild type (+) and CKR5 32 deletion in 738 homosexual male Caucasians show a significant difference of frequencies among HIV-1 infected and non infected individuals (p=200000). • The other loci (CD4, chemokine SCYAL, HLADQAL, TCRA,TCRB) on the other hand did not show such a significance.
