JC polyomavirus whole genome sequencing at the single molecule level reveals emerging viral populations in Progressive Multifocal Leucoencephalopathy
JC polyomavirus (circular genome) contains two opposite coding regions separated by the regulator non-coding control region (NCCR). NCCR rearrangements and missense mutations in the viral capsid protein VP1 gene differentiate JCV prototype genomes recovered from PML lesions from archetype urine strains. To further investigate the emerging variability of JCV populations in PML, we deep sequenced JCV whole genome recovered from CNS and/or urine samples from HIV- and non HIV-infected PML patients, using single-molecule real-time sequencing (PacBio, Paci?c Biosciences). Phylogenetic analysis showed that PML strains distributed among 6 of 7 known genotypes. Whole genome single molecule sequencing provides insight in the genesis of JCV neurotropic populations.
