All data in the bottom row of Table II should have been shifted one column to the right. The corrected table appears below.

Table II.

^aTotal RNA was prepared from PBL from all the patients and controls, except for donor C2; buffycoat was obtained and CD27 positive B cells were used.

^bFR, framework region.

^cToo few mutations to give a reliable ratio.
