  1. Significant difference of the contribution of mutations of RGYW/WRCY sequences to all mutations comparing nonproductive and productive Vλ gene rearrangements: *P = 0.018 (chi-square test), peripheral blood B cells from the patient with SS; P = 0.049, B cells from the parotid gland; and P < 0.0001, B cells from the peripheral blood of NHS [27].
