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 GeneticsNov 19, 2024The c.148C>T (p.H50Y) alteration is located in exon 2 (coding exon 2) of the IL17C gene. This alteration results from a C to T substitution at nucleotide position 148, causing the histidine (H) at amino acid position 50 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
