FIG. 3.

Detection of HERV-K(HML2) preinsertion sites. Amplification of solo LTR loci within the published human genome sequence showed a preinsertion site (PRE), a solo LTR (sLTR), or a full-length element (FULL) when tested against a panel of 19 individuals. The provenance of each individual is shown in Table 1, and allele frequencies are shown in Table 2. The identity of each band was confirmed by DNA sequencing. We rescreened the previously identified polymorphism 165c5, as the originally estimated frequencies were based largely on individuals from Russia (25).
