No significant modification of BAFF-R mRNA expression (12/191 (6.3%) vs 3/120, (2.5%); p=0.18), or phenotypic expression (3873 vs 4771, mean difference: -868, 95% CI: -2086 to 650; p=0.24) (Figure 3B) was evidenced between autoreactive cells collected at baseline and those collected after CS treatment. Here, TNFRSF13C is linked to Cowden syndrome 1.
