361 Japanese subjects: 95 HIV-1-infected patients (48 nonprogressors and 47 slow progressors) and 266 controls 453 Indian subjects: 251 HIV-1-infected patients and 202 controls
No evidence of association between the APOBEC3B deletion and susceptibility to HIV infection and AIDS
1,124 individuals with HCC, 510 individuals with persistent HBV infection, and 826 healthy controls. All subjects were of Han Chinese ethnicity
Higher frequency of the APOBEC3B deletion allele in persistent HBV carriers () and HCC patients () compared to controls Presence of at least one deletion allele was associated with an increased risk for persistent HBV infection () and HCC development ()
179 HBV chronic carriers and 216 healthy control subjects from the Moroccan population
No significant difference in the frequency of deleted APOBEC3B alleles between patients with chronic hepatitis B and control subjects Subjects carrying the Del/Del genotype displayed a trend for increased susceptibility to HBV infection compared to the wild type genotype () Carriers of the APOBEC3B deletion had significantly lower viral loads than patients with the wild type genotype ()
3,073 participants enrolled in six HIV/AIDS prospective cohorts: 1,481 European Americans, 949 African Americans from five US-based cohorts, and 643 patients enrolled in the Swiss HIV cohort
For African Americans, the variant allele 186R was strongly associated with a decline of CD4+ T cells ()
773 white French individuals: 327 HIV-1+ (245 slow progressors; 82 rapid progressors) and 446 healthy control subjects of similar ethnic origin
29 polymorphisms with allele frequencies >1% were identified No significant associations were found between the polymorphisms or haplotypes and disease progression
136 adult HIV-infected patients from the Western Australian HIV cohort
22 single nucleotide polymorphisms were identified No significant association of these APOBEC3G genetic variants and the presence of HIV-1 hypermutation was found (although an intronic allele 6892C was marginally associated with HIV-1 hypermutation)
250 South African women at high risk for HIV-1 subtype C infection
The H186R mutation and a 3′ extragenic mutation (rs35228531) were associated with high HIV viral loads ( and ) and decreased CD4+ T-cell counts ( and )
534 children perinatally exposed to HIV-1 (109 exposed uninfected and 425 HIV-1-infected), from a pediatric cohort of white-Hispanic ethnicity from Argentina
HIV-1 perinatal transmission and progression to AIDS were not affected by APOBEC3G H186R or APOBEC3G C40693T APOBEC3G C40693T was correlated with substitutions in Vif motifs involved in the interaction with APOBEC3G ()
400 HIV-1-infected individuals naive to drug therapy from the Brazilian population
Seven loci were analyzed: SNP −571 (rs5757463); −199 (rs34550797); −90 (rs5750743); 119 (rs5757465); 186 (rs8177832); 197 (rs3736685); 199 (rs2294367) For the SNP −571, heterozygous (C/G) and homozygous (G/G) individuals had lower CD4+ T-cell counts compared to homozygous (C/C) individuals ()
1,049 HIV-1-infected children from the Pediatric AIDS Clinical Trials Group (PACTG) protocols P152 and P300 (60% non-Hispanic black, 26% Hispanic, 13% non-Hispanic white, and 1% other or unknown race/ethnicity)
APOBEC3G H186R homozygous G/G genotype was associated with faster HIV-1 disease progression () and central nervous system (CNS) impairment () APOBEC3G F119F-C allele was associated with protection against disease progression and CNS impairment in both additive and dominant models ( and , resp.) and CNS impairment ( and , resp.)
70 Italian HIV-exposed seronegative individuals and their HIV-1-infected sexual partners
The APOBEC3H haplotype I was found in a higher frequency in the exposed seronegative compared to the HIV+ individuals (), suggesting a protection from sexually transmitted HIV-1 infection
68 SNPs were analyzed Homozygous carriers of an APOBEC3H risk haplotype (A3Hrh) had lower GA→AA (A3F) sequence editing on proviral HIV-1 vif sequence () and lower HIV-1 RNA levels ()
