Genetic variability of the G glycoprotein gene of human metapneumovirus.

ABSTRACT: Human metapneumovirus (hMPV) has been associated with respiratory illnesses like those caused by human respiratory syncytial virus (HRSV) infection. Similar to other pneumoviruses, genetic diversity has been reported for hMPV. Little information is currently available on the genetic variability of the G glycoprotein (G), which is the most variable gene in RSV and avian pneumovirus. The complete nucleotide sequences of the G open reading frame (ORF) of 24 Canadian hMPV isolates were determined. Phylogenetic analysis showed the existence of two major groups or clusters (1 and 2). All but one of the hMPV isolates that we examined belonged to cluster 1. Additional genetic variability was observed in cluster 1, which separated into two genetic subclusters. Within cluster 1 the nucleotide sequen
