Genes affected

IRAK3 (HGNC:17020): (interleukin 1 receptor associated kinase 3) This gene encodes a member of the interleukin-1 receptor-associated kinase protein family. Members of this family are essential components of the Toll/IL-R immune signal transduction pathways. This protein is primarily expressed in monocytes and macrophages and functions as a negative regulator of Toll-like receptor signaling. Mutations in this gene are associated with a susceptibility to asthma. Alternate splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

Collection Method:clinical testing

The c.226T>C (p.W76R) alteration is located in exon 2 (coding exon 2) of the IRAK3 gene. This alteration results from a T to C substitution at nucleotide position 226, causing the tryptophan (W) at amino acid position 76 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
