Inborn errors of the IL-17-mediated signaling have been associated with chronic mucocutaneous candidiasis (CMC). We describe a patient with CMC, atopic dermatitis, enamel dysplasia, and recurrent parotitis harboring a novel compound heterozygous mutation of TRAF3IP2, leading to autosomal recessive ACT1 deficiency and deficient IL-17 signaling.

Although bacterial meningitis is a rare presentation of a congenital immunodeficiency, invasive meningococcal disease (IMD) is classicaly associated with complement deficiencies. We report a patient from a consanguineous kindred presenting with an IMD caused by serogroup B meningococcus that revealed an underlying C5 deficiency caused by a novel mutation in the C5 gene.
