Phylogenetic tree based on complete U8 sequences. Numbers along links refer to nucleotide positions. Open boxes are nodes from which other (not shown) sequences branch. A, C, indicate transversions; "d" deletions and "i" insertions. Star has the following mutations with respect to rCRS: 73, 263, 311i, 750, 1438, 2706, 4769, 7028, 8860, 11719, 14766 and 15326 and the following ones respect to L3*: 8701, 9540, 10398, 10873, 12705, 15301, 16223, 16519. Subject origins are: Dutch (Dut86; [38]), Spanish (Spa) and Italian (Ita) [20], 3 Finns (Fin; [14]). British-Australian (BriT7; Obayashi T, Tanaka M, personal communication), Jordan (Jor767) and 4 Basques (Bq 1820, 30, 47, 24)
