Archetype JC polyomavirus prevails in a rare case of JC polyomavirus nephropathy and in stable renal transplant recipients with JC polyomavirus viruria.

JC polyomavirus (JCPyV) is reactivated in approximately 20% of renal transplant recipients and it may rarely cause JCPyV-associated nephropathy (JCPyVAN). Whereas progressive multifocal leukoencephalopathy of the brain is caused by rearranged neurotropic JCPyV, little is known about viral sequence variation in JCPyVAN due to the rarity of this condition.Using single-molecule real-time sequencing, characterization of full-length JCPyV genomes from urine and plasma of one JCPyVAN patient and twenty stable renal transplant recipients with JCPyV viruria was attempted. Sequence analysis of JCPyV strains was performed with the emphasis on the NCCR region, the major capsid protein gene VP1 and the large T…
