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
Classification made for transcript
Verdict is Pathogenic. Variant got 10 ACMG points.
PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.11033193 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP3
Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF, max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Rady Children's Institute for Genomic Medicine, Rady Children's Hospital San Diego | Feb 04, 2020 | A hemizygous c.1303-2A>G variant in IRAK1 was detected in this individual. This variant affects the canonical splice acceptor site of intron 10 of 13, and is therefore predicted to interfere with splicing and result in loss of normal protein function. This variant has not been previously reported or functionally characterized in the literature to our knowledge. It is absent from the ExAC and gnomAD population databases and thus is presumed to be rare. Multiple splice prediction tools suggest this variant is likely to interfere with normal splicing. The IRAK1 gene is highly intolerant of loss of function variants (pLI: 1.00). Based on the available evidence, the c.1303-2A>G variant is classified as a Variant of Uncertain Significance - |
