Additionally, SLE patients with Thr/Thr187 and Ile/Thr187 genotypes were more likely to have pleural effusions (P = 0.038, OR 1.874 [95% CI 1.033-3.411]) and anti-SSA/Ro antibody production (P = 0.046, OR 2.221 [95% CI 1.013-4.897]).
In conclusion, in this small case series we showed that MYD88 L265P mutation analysis could serve as a useful adjunct in distinguishing benign from lymphomatous PE in patients with LPL.
