Genes affected
IL17F (HGNC:16404): (interleukin 17F) The protein encoded by this gene is a cytokine that shares sequence similarity with IL17. This cytokine is expressed by activated T cells, and has been shown to stimulate the production of several other cytokines, including IL6, IL8, and CSF2/GM_CSF. This cytokine is also found to inhibit the angiogenesis of endothelial cells and induce endothelial cells to produce IL2, TGFB1/TGFB, and monocyte chemoattractant protein-1.

This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 157 of the IL17F protein (p.Pro157Ala). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with IL17F-related conditions. ClinVar contains an entry for this variant (Variation ID: 1026711). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
