In the head-to-head post-hoc Mann-Whitney analyses, miR-206 was found to be significantly deregulated in patients with APS as compared to HCs, while miR-224-5p significantly differed in BS and HCs; conversely, no significant difference was found between BS and APS when the three ci-miRNAs were analysed as single markers. Here, NDUFB6 is linked to autoimmune polyendocrinopathy.
