FOXP3 and disease of the tendon: It has been observed that relative to the combined wild-type genotype (FCRL3 –169TT and FOXP3 –2383CC), the combined variant genotype (FCRL3 –169TC or –169CC and FOXP3 –2383CT or –2383TT) were associated with an increased risk of developing tendinopathy among athletes who present tendon pain (WT/VAR: OR = 2.24; 95% CI: 1.14–4.40 and VAR/VAR: OR = 2.60; 95% CI: 1.11–6.10) or were away from training due pain (VAR/VAR: OR = 5.00; 95% CI: 1.12–22.30).
