INTRODUCTION.
Chromosomes #3 has two (2) genes of HIV Infection Resistance.
Genomic coordinates 3:46,354,111-46,360,940 and 3:46,370,142-46,376,206 are cytogenetic location 3p21.31 sites of HIV Infection Resistance genes CCR2 and CCR5 located on chromosome #3. 
The screenshots of 6,830 bp (base pairs) of the CCR2 gene is shown ABOVE; and 6,065 bp (base pairs) of the CCR5 gene is shown BELOW. 
Eight (8) other genes besides CCR2 and CCR5 in the 3p21.31 cytogenetic location are listed BENEATH.
