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.
Method: Subsequently, nucleotide identities at position 109, 131, 132, 143, 145, 178, 350 were determined with a Pyromark Q96 MD (Qiagen, Valencia, CA, USA) to identify the variants AA/NA-1, Af1, Af2, As, E-
C109G, E-
G131G, E-G350, Em, Ep.
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.
