[Polymorphism analysis of human cytomegalovirus UL150 gene in low passage clinical isolates].
OBJECTIVE
To investigate the polymorphism of human cytomegalovirus UL150 gene in low passage clinical isolates and try to study the relationship between the polymorphism and different pathogenesis of congenital HCMV infection.


METHODS
PCR was performed to amplify the entire HCMV UL150 gene region of 29 clinical isolates, which had been proven containing detectable HCMV-DNA by using FQ-PCR. PCR amplification products were sequenced directly and the data were analysed.


RESULTS
25 among 29 isolates were amplified and 18 isolates were sequenced successfully. By comparison with the sequence of Toledo and Merlin, the length of UL150 ORFs in all 18 clinical isolates was similar to that of Merlin than Toledo.


CONCLUSIONS
HCMV UL150 DNA and deduced amino acid sequences is hypervariability.
