Deduced amino acid sequence alignment of the VP4 genes of the current HuRVC study strain with that of previously-described HuRVC strains. The dots represent the identical amino acids. Six mutations were noticed at positions 31, 73, 124, 141, 146 and 192, indicated in red boxes. Of note, one change was linked with the N-glycosylation site at position 192 (N192S) in the study strain.
