FCRL3 and thyroid gland disorder: To evaluate possible associations of FCRL expression with thyroid antibodies, we have checked if medians of relative mRNA expression of particular FCRL subtypes (FCRL2, FCRL3, FCRL4) differ between patients with positive vs. negative thyroid antibodies (TPOAb (+) vs. TPOAb (−); TgAb (+) vs. TgAb (−); TSHRAb (+) vs. TSHRAb (−)).
