Genotyping distinction between HPV-16 and HPV-31 may need a 50-base sequence. HPV DNA isolated from a clinical sample with its partial L1 gene DNA sequence of 50 bases is validated as HPV-16 strain SRB236AK L1 protein (L1) gene by the GenBank database. However, HPV-31 isolate N5 and some HPV-33 major capsid protein L1 genes share an identical 34-base sequence on the upstream (right) segment in this region with this variant of HPV-16. Genotyping error might have occurred if only the 34 bases on the right were selected for sequence alignment algorithm.
