DNA and predicted amino acid sequences of TCR BV 5.1 clonotypes selected for hybridization experiments. For each clonotype, a portion of the BV and BJ regions and the complete CDR3 loop region is shown. The CDR3 length and BJ utilization are indicated for each clonotype. CDR3-specific oligonucleotide probe names are shown on the left and the sequence for each is underlined. A shared CDR3 loop region motif (P G T G) present in both HITT patients is highlighted in bold.
