Genes affected
IL17C (HGNC:5983): (interleukin 17C) The protein encoded by this gene is a T cell-derived cytokine that shares the sequence similarity with IL17. This cytokine was reported to stimulate the release of tumor necrosis factor alpha and interleukin 1 beta from a monocytic cell line. The expression of this cytokine was found to be restricted to activated T cells. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 08, 2022The c.449G>A (p.R150Q) alteration is located in exon 3 (coding exon 3) of the IL17C gene. This alteration results from a G to A substitution at nucleotide position 449, causing the arginine (R) at amino acid position 150 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
