Red List (low evidence)

Strong evidence links IL17 to mucocutaneous immunity against fungal infection, but only one case of heterozygous IL17F mutation has been described with CMC (another family member bearing the same variant was asymptomatic)

I don't know

Comment on list classification: Green to Amber rating after further discussion with external clinical expert. Agree only one family reported, although some cellular supporting information, which is not enough evidence to make it Green

Comment on list classification: Changed Amber to Green from external expert review and further publications to support gene-disease association

Comment on mode of inheritance: PMID: 21350122 concluded that the autosomal dominant chronic mucocutaneous candidiasis in this kindred results from a hypomorphic, dominant-negative IL17F allele, which impairs the receptor binding and bioactivity of both IL17F homodimers and IL17A-IL17F heterodimers. I cannot find evidence of AR inheritance.

This gene was absent from the original PanelApp PID panel dataset (review April 2018). However it was listed in external expert immunodeficiency diagnostic gene list(s) GOSH or GRID. In this combined PID panel, this gene has been rated as AMBER and needs further curational review to assess pertinence prior to v1.
