Genes affected

IL17B (HGNC:5982): (interleukin 17B) The protein encoded by this gene is a T cell-derived cytokine that shares sequence similarity with IL17. This cytokine was reported to stimulate the release of TNF alpha (TNF) and IL1 beta (IL1B) from a monocytic cell line. Immunohistochemical analysis of several nerve tissues indicated that this cytokine is primarily localized to neuronal cell bodies. Alternative splicing results in multiple splice variants.

The c.449G>A (p.R150H) alteration is located in exon 3 (coding exon 3) of the IL17B 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 histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
