Notably, two (patients T24 and T31) showed remarkably high IL‐17A‐ and IL‐17F‐binding and had candidiasis (Supporting information Table S2); nevertheless, these antibodies cannot be a strong predisposing factor, as two other patients with CMC and five with intercurrent Candida infections tested negative against IL‐6 (Table S2). Here, IL17F is linked to candidiasis.
