Genes affected

TLR9 (HGNC:15633): (toll like receptor 9) The protein encoded by this gene is a member of the Toll-like receptor (TLR) family, which plays a fundamental role in pathogen recognition and activation of innate immunity. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. They recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity. Studies in mice and human indicate that this receptor mediates cellular response to unmethylated CpG dinucleotides in bacterial DNA to mount an innate immune response. [provided by RefSeq, Aug 2017]

The c.3043A>G (p.R1015G) alteration is located in exon 2 (coding exon 2) of the TLR9 gene. This alteration results from a A to G substitution at nucleotide position 3043, causing the arginine (R) at amino acid position 1015 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
