Human cytomegalovirus (HCMV) displays genetic polymorphisms. HCMV disease and tissue tropism may be related to specific genomic variability among strains. This work analyzed the genetic polymorphism of UL141 open reading frame (ORF), one of the genes in HCMV UL/b′ region, from 21 clinical strains. 8 previously published UL141 sequences in the GenBank were used for sequence comparison. Detailed sequence analysis showed that the UL141 gene was highly conserved at both the nucleotide and amino acid level. The coding regions were identical in size. The nucleotide and amino acid sequence identities among all strains were 96.9–100% and 97.6–100%, respectively.
