Oral candidiasis and seborrheic dermatitis in an 8-year-old female with a heterozygous variant of the IL-17RC gene.

An 8-year-old female with chronic oral candidiasis and severe seborrheic dermatitis was found to have a heterozygous mutation (p.R14X c.40 C>T) of the IL-17RC gene, which was predicted to possibly represent a new pathogenic variant via truncation or nonsense-mediated mRNA decay. Given previously reported IL-17RC-related disorders are autosomal recessive, we would expect an affected individual to have two mutated alleles whereas our patient was heterozygous. Given the overlapping clinical picture, this variant could be responsible for altered immunity against both Candida and Malassezia species. This is the first report to our knowledge of chronic oral candidiasis and severe seborrheic dermatitis in a patient with a heterozygous variant (p.R14X c.40 C>T) for the IL-17RC gene.© 2023 Wiley Periodicals LLC.
