Genes affected

IL13RA1 (HGNC:5974): (interleukin 13 receptor subunit alpha 1) The protein encoded by this gene is a subunit of the interleukin 13 receptor. This subunit forms a receptor complex with IL4 receptor alpha, a subunit shared by IL13 and IL4 receptors. This subunit serves as a primary IL13-binding subunit of the IL13 receptor, and may also be a component of IL4 receptors. This protein has been shown to bind tyrosine kinase TYK2, and thus may mediate the signaling processes that lead to the activation of JAK1, STAT3 and STAT6 induced by IL13 and IL4.

The c.1066G>A (p.V356I) alteration is located in exon 9 (coding exon 9) of the IL13RA1 gene. This alteration results from a G to A substitution at nucleotide position 1066, causing the valine (V) at amino acid position 356 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
