ABSTRACT We analyzed xenotropic murine leukemia virus-related virus (XMRV) integration site sequences previously identified from human prostate tissues for single nucleotide polymorphisms (SNPs) to discriminate between patient and potential cell line sources of the proviruses. The SNPs of two integration sites were identical to those in cell lines but not the patients, whereas the data on the remaining 12 integration sites were inconclusive. Our results provide direct evidence for contamination during analysis of XMRV integration sites.
