Abstract: Among HPV-16-positive cases, 37% were identified as prototype variant Ep, and 63% were nonprototypes: 33% Em, 12% E-
G131G, 5% Af1, 4% AA/NA-1, 3% E-
C109G, 3% E-
G131T, 2% As, and 1% Af2.
Discussion: in
anal neoplasia tissue from a mostly HIV positive population, which may support their hypothesis that infection with the E-
G131G or E-
G131T genotypes pose elevated risk for malignant progression.
