Genes affected

TIRAP (HGNC:17192): (TIR domain containing adaptor protein) The innate immune system recognizes microbial pathogens through Toll-like receptors (TLRs), which identify pathogen-associated molecular patterns. Different TLRs recognize different pathogen-associated molecular patterns and all TLRs have a Toll-interleukin 1 receptor (TIR) domain, which is responsible for signal transduction. The protein encoded by this gene is a TIR adaptor protein involved in the TLR4 signaling pathway of the immune system. It activates NF-kappa-B, MAPK1, MAPK3 and JNK, which then results in cytokine secretion and the inflammatory response. Alternative splicing of this gene results in several transcript variants; however, not all variants have been fully described. [provided by RefSeq, Jul 2008]

TIRAP (HGNC:):

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• PP3: Multiple lines of computational evidence support a deleterious effect 7: AlphaMissense, Cadd, Dann, Eigen, FATHMM_MKL, phyloP100way_vertebrate, PROVEAN [when BayesDel_addAF, BayesDel_noAF, max_spliceai, MetaRNN, MutationTaster was below the threshold]
• BP4: Computational evidence support a benign effect (MetaRNN=0.037235945).
• BP6: Variant 11-126292695-G-A is Benign according to our data. Variant chr11-126292695-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 1285058.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr11-126292695-G-A is described in Lovd as [Likely_benign].
• BS2: High Homozygotes in GnomAdExome4 at 15 gene
