Rostamzadeh et al. (2015) observed up-regulation of FCRL2 mRNA expression not only in GD but also in Hashimoto thyroiditis (HT) patients compared to healthy individuals, as well as the increased FCRL4 mRNA expression in GD patients (similarly to our results) but not in HT patients [11]. This evidence concerns the gene FCRL2 and Hashimoto thyroiditis.
