Members of the genus Metapneumovirus possess 8 genes. They lack the two promoter proximal NS1 and NS2 genes found in the members of the genus Orthopneumovirus. The gene order is N-P-M-F-M2-SH-G-L. Alignment of the L proteins of the metapneumoviruses shows a moderate level of conservation between the human and avian viruses. Their genome length is smaller than that of the members of the other genus.
Members of the genus Orthopneumovirus possess 10 genes including two NS1 and NS2 which are promoter proximal (i.e. before) the N gene. The gene order is NS1-NS2-N-P-M-SH-G-F-M2-L. Alignments of the L proteins show moderate conservation of the sequences between the human, murine, bovine and ovine viruses. Their genome length is larger than that of the members of the other genus.
