Genes affected

TLR5 (HGNC:11851): (toll like receptor 5) This gene encodes a member of the toll-like receptor (TLR) family, which plays a fundamental role in pathogen recognition and activation of innate immune responses. These receptors recognize distinct pathogen-associated molecular patterns that are expressed on infectious agents. The protein encoded by this gene recognizes bacterial flagellin, the principal component of bacterial flagella and a virulence factor. The activation of this receptor mobilizes the nuclear factor NF-kappaB, which in turn activates a host of inflammatory-related target genes. Mutations in this gene have been associated with both resistance and susceptibility to systemic lupus erythematosus, and susceptibility to Legionnaire disease.[provided by RefSeq, Dec 2009]

ACMG classification

Verdict is Benign. Variant got -16 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004293859).
• BP6: Variant 1-223111102-T-A is Benign according to our data. Variant chr1-223111102-T-A is described in ClinVar as [Likely_benign]. Clinvar id is 252618.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-223111102-T-A is described in Lovd as [Benign].
• BS2: High Homozygotes in GnomAd4 at 5 AR gene
