Genes affected

IL36B (HGNC:15564): (interleukin 36 beta) The protein encoded by this gene is a member of the interleukin 1 cytokine family. Protein structure modeling indicated that this cytokine may contain a 12-stranded beta-trefoil structure that is conserved between IL1A (IL-A alpha) and IL1B (IL-1 beta). This gene and eight other interleukin 1 family genes form a cytokine gene cluster on chromosome 2. Two alternatively spliced transcript variants encoding distinct isoforms have been reported.

Collection Method: clinical testing

The c.61G>A (p.V21M) alteration is located in exon 3 (coding exon 2) of the IL36B gene. This alteration results from a G to A substitution at nucleotide position 61, causing the valine (V) at amino acid position 21 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
