A: the first conserved region containing the endocytosis signal. B: the region containing the Kennedy-like sequences. C: the hydrophobic region D: LLP-2 domain. E: LLP-3 domain. F: LLP-3 / LLP-1 inter-region. G: LLP-1 region. ND: not determined. * Group A, B, provirus, virus alignement SE were normalized with the natural logarithm of the number of sequences. ** Results of the intra-patient study.
