Abstract: This study of
gp41 polymorphisms showed that insertions in the fourth threonine (74.8%) and
L7M substitutions (85.3%) were more frequent in the fusion peptide motif in Korean HIV-1 isolates compared with those from other countries.
Introduction: In addition, many of the FPs in Korean HIV-1 isolates had
L7M substitutions near the FLGFL motif.
Introduction: Table 1 shows that the dominant mutation was a T-insertion mutation (n=122, 74.8%), while an
L7M substitution near the FLGFL motif was also frequent in
HIV-1-infected patients (n=139, 85.3%).
