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 (−)). The gene discussed is FCRL2; the disease is thyroiditis.
