| a survey for 32 nucleotide deletion in the ccr-5 chemokine receptor gene (deltaccr-5) conferring resistance to human immunodeficiency virus type 1 in different ethnic groups and in chimpanzees. | the 32 nucleotide deletion in the ccr-5 chemokine receptor gene referred to as deltaccr-5 has been shown to confer resistance to hiv-1. using pcr, 1,105 human subjects and 33 common chimpanzees were genotyped attributing them to one of the three possible genotypes: wild-type homozygote (w/w); deltaccr-5 homozygote (deltaccr-5/deltaccr-5) and deltaccr-5/wild-type heterozygotes (deltaccr-5/w). the ethnic groups investigated included different middle eastern nationalities (mainly arab) and russians ... | 1998 | 9598936 |
