FCRL4 and hyperthyroidism: Instead, FCRL4 mRNA expression was higher in patients with hyperthyroidism (subclinical + overt) than in euthyroid patients (2.509 vs. 0.995, p = 0.001) when the whole group of individuals was considered (Figure 4C, left) as well as when only GO + GD was considered (2.509 vs. 1.073, p = 0.004) (Figure 4C, right).
