Genes affected

IRAK2 (HGNC:6113): (interleukin 1 receptor associated kinase 2) IRAK2 encodes the interleukin-1 receptor-associated kinase 2, one of two putative serine/threonine kinases that become associated with the interleukin-1 receptor (IL1R) upon stimulation. IRAK2 is reported to participate in the IL1-induced upregulation of NF-kappaB. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.054671377).

May 03, 2023

The c.449A>G (p.Q150R) alteration is located in exon 4 (coding exon 4) of the IRAK2 gene. This alteration results from a A to G substitution at nucleotide position 449, causing the glutamine (Q) at amino acid position 150 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
