TRAJ24*01 vs TRAJ24*02 #327

Reported by Jamie Heather

About 2/3 of the ~400 human TCR entries reportedly making use of TRAJ2401 are actually probably using TRAJ2402. There's a two nt mismatch between them that corresponds to a two AA FGXG-proximal mismatch:

TTDSWGKFEFGAGTQVVVTP       TRAJ24*01
TTDSWGKLQFGAGTQVVVTP       TRAJ24*02
       ^^

It'd take a lot of deletion to make 02 into 01 it's pretty likely that most of the '-WGKLQF' CDR3s (which is the majority) are actually *02.
