Result: Global sequence analysis showed that the most frequent amino acid substitutions in RT were S162C (29.4%), T200A (35.3%), M184V (32.3%), L214F (67.6%), I135T (55.9%), D177E (26.5%) and E122K (44.1%), and the most in PR were V15I (41.2%), M36I (38.2%) and E35D (23.5%).
Discussion: The other substitutions found in co-infected patients, E122K (44.1%), T200A (35.3%), S162C (29.4%) and D177E (26.5%) have been previously reported in studies with HIV mono-infected patients.
Mutations in the reverse transcriptase and protease genes of human immunodeficiency virus-1 from antiretroviral naive and treated pediatric patients.
Abstract: Polymorphism mutation sites with mutation rates in the RT region higher than 60.0% were: I135A/L/M/R/T/V 93.5%, T200A/E/I/P/V 89.7%, Q278E/K/N/T 88.8%, S162C/Y 82.2%, and K277R/S 66.4%.
Result: The sites with mutation rates higher than 60.0% included: I135A/L/M/R/T/V 93.5% (100/107), among which I135V was 80.4% (86/107); T200A/E/I/P/V 89.7% (96/107), among which T200A was 81.3% (87/107); Q278E/K/N/T 88.8% (95/107), among which

Abstract: E53D (97%), I135V/T/R (81%), S162C (94%), Q207E (100%), and R211K (97%) were primarily in CRF_08BC subtypes and D121Y/H (97%) were primarily in CRF_07BC.
