RT-PCR indicates reverse transcriptase–polymerase chain reaction.
The junctional region is described as the number of bases lost at the 3′ end of the segment followed by randomly inserted nucleotides and the number of bases lost from the 5′ end of the J segment.
Frame of the junctional region: +, in-frame, without stop codons in the junctional region; −, out-of-frame.
ND indicates not determined; +, present; −, absent.
+ indicates V segments with more than 2% somatic mutations; −, less than 2% somatic mutations; NI, not identified, because the rearrangement could not be amplified.
NA indicates not applicable, because only one intact chromosome 2 was present, although 2 rearrangements seemed to be present in Southern blot analysis (see text).
