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]

IRAK3 Gene-Disease associations (from GenCC):

• asthma-related traits, susceptibility to, 5

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.922

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.85T>G (p.C29G) alteration is located in exon 1 (coding exon 1) of the IRAK3 gene. This alteration results from a T to G substitution at nucleotide position 85, causing the cysteine (C) at amino acid position 29 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
