a

In house, Cytocell and Vysis probe sets were used (Fig. 1, Table 1, and text).

b

Cell lines in bold have one or more detection discrepancies among the three probe sets.

c

Normal fusion signals (F) are defined as paired CH/VH signals seen on a normal chromosome 14 or on a derivative chromosome

d

#CH, VH signals is the total number of paired (F) and discrete CH or VH signals observed for different IGH rearrangements. Detection discrepancies (only with the Vysis LSI 3′ Flanking probe) are shown in parentheses, with the bold CH signals identified with the in-house and Cytocell probes but not by the Vysis probe.

e

Type of rearrangement: simple CH insertion (I); complex insertion (CI); non-variant translocation not involving a primary partner (T); primary translocation (PT); variant translocations (VT1a, VT1b, VT2). Brackets indicate rearrangements already accounted for. See text for additional details.

f

Derivative which contains VH signal underwent further rearrangement.

g

CH signal originated from primary translocation.
