Genes affected

IRAK1 (HGNC:6112): (interleukin 1 receptor associated kinase 1) This gene encodes the interleukin-1 receptor-associated kinase 1, one of two putative serine/threonine kinases that become associated with the interleukin-1 receptor (IL1R) upon stimulation. This gene is partially responsible for IL1-induced upregulation of the transcription factor NF-kappa B. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.006942272).
• BS2: High Hemizygotes in GnomAd4 at 18 gene

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1924G>A (p.V642M) alteration is located in exon 12 (coding exon 12) of the IRAK1 gene. This alteration results from a G to A substitution at nucleotide position 1924, causing the valine (V) at amino acid position 642 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
