Genes affected

IL33 (HGNC:16028): (interleukin 33) The protein encoded by this gene is a cytokine that binds to the IL1RL1/ST2 receptor. The encoded protein is involved in the maturation of Th2 cells and the activation of mast cells, basophils, eosinophils and natural killer cells. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]

Dec 20, 2023

The c.471T>G (p.D157E) alteration is located in exon 6 (coding exon 5) of the IL33 gene. This alteration results from a T to G substitution at nucleotide position 471, causing the aspartic acid (D) at amino acid position 157 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
