Parentheses indicate the oligonucleotides with which monoclonal rearrangements were demonstrated.
The Vγ segments used were determined using Vγ specific PCR experiments and confirmed by sequencing.
Abbreviations: C, monoclonal rearrangements; P, polyclonal pattern; O, oligoclonal pattern; MLN, mesenteric lymph nodes.
