In the article entitled “Kaposi sarcoma-associated herpesvirus infects monotypic (IgMγ) but polyclonal naive B cells in Castleman disease and associated lymphoproliferative disorders,” which appeared in the April 1, 2001, issue of Blood(97:2130-2136), Tables 3 and 4 should have appeared as follows.

Clones with frequent mutations (> 10) were occasionally seen. They are most likely from reactive B cells rather than KSHV-positive plasmablasts and are not included.
S indicates silent mutation; R, replacement change; —, no mutation; LN, lymph node; Sp, spleen.
