Genes affected

IL13RA2 (HGNC:5975): (interleukin 13 receptor subunit alpha 2) The protein encoded by this gene is closely related to Il13RA1, a subuint of the interleukin 13 receptor complex. This protein binds IL13 with high affinity, but lacks cytoplasmic domain, and does not appear to function as a signal mediator. It is reported to play a role in the internalization of IL13.

The c.845C>T (p.T282I) alteration is located in exon 7 (coding exon 6) of the IL13RA2 gene. This alteration results from a C to T substitution at nucleotide position 845, causing the threonine (T) at amino acid position 282 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
