Supplementary Figure S1. Restriction map of the integrated HHV-6B genomes. Restriction enzymes used for the analyses are as
follows: MseI (M) (a), PstI and BglII (P and B) (b), and SacI (S) (c). Probes are denoted by small horizontal bars. The expected sizes of the
detected restriction fragments are indicated above the schematic diagrams. Diagrams are shown for standard cases (upper panels) as well
as cases 28 that include three DR copies (lower panels).
Supplementary Figure S2. PCR analyses of the TRS-1 site within the DR-R region (a) and TRS-2 of the DR-L region (b) of HHV-6.
The bracket and arrowhead denote authentic products. Lane M, size markers; lane 1, case 18; lane 2, case 19; lane 3, case 20; lane 4, case
28; lane 5, case 31; lane 6, case 63; lane 7, non-CIHHV-6 case; lane 8, water control. Telomere repeat numbers are indicated below the
panel.
Supplementary Figure S3. Southern blot analyses of genomic DNA from the
CIHHV-6B study subjects. The restriction enzymes used for these analyses are
indicated above the panels. In each panel, the data with a DR probe is shown on the left
side, while the data with a probe located at the distal end of the UL region (flanking to the
DR) is shown on the right. All of the gels have been run under the same experimental
conditions. Triangles indicate bands derived from the DR-R, while arrows indicate the
smears derived from the DR-L. The restriction fragments for DR-R are large enough to
include two copies of DRs. On the other hand, the restriction fragments for DR-L
manifest as smears and the sizes correspond to one copy of the DR. Size markers are
indicated on the left. Lane 1, case 18; lane 2, case 28; lane 3, non-CIHHV-6 case.
Supplementary Figure S4. Comparison of the restriction map of the integrated HHV-6B genomes in cases 18 and 28. Restriction
enzymes used for the analyses are as follows: EcoRI (E) (a), NdeI (Nd) (b), and NcoI (N) (c). Probes are denoted by small horizontal bars.
DR probes are indicated by black bars, while probes located at the distal end of the UL region are indicated by white bars. The expected
sizes of the detected restriction fragments are indicated above the schematic diagrams. Diagrams are shown for standard case, case 18
(upper panels). For case 28 that include three DR copies, two possibilities exist: two of the three copies might be located at the proximal
region (middle panels) or at the distal region (lower panels).
Supplementary Figure S5a. PCR analysis of the junction of the two DRs in HHV-6B.
The arrowhead denotes authentic products. The sizes of the PCR products from cases 28
and 63 are lower than that from the replicating viruses from a patient with exanthema
subitum. Lane M, size markers; lane S, sample from a patient with exanthema subitum;
lane 1, case 18; lane 2, case 19; lane 3, case 20; lane 4, case 28; lane 5, case 31; lane 6,
case 63; lane 7, non-CIHHV-6 case; lane 8, water control.
Supplementary Figure S5b. Southern blot analysis for the long range PCR using
telomeric primer. To show the specificity of the PCR products appearing as a smear in
Figure 4, we performed Southern hybridization using telomere repeat probe. The results
indicated that the PCR products really contained telomeric repeats. Size markers are
indicated on the left. Lane 1, non-CIHHV-6 case; lane 2, case 28; lane 3, case 18.
