The variant received -1 classification points (ACMG Germline Pathogenicity v2019). PM2BP4_ModerateBP7

The NM_017442.4(TLR9):c.1635G>T (p.Pro545Pro) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.0000143 (AC=23) in the gnomAD database across 1,612,914 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000121. In-silico predictor (REVEL) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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]

Classification according to ACMG Germline Pathogenicity v2019

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 points.

PM2
Very rare in gnomAD for AR/unknown gene (popmax AF < threshold/10) — PM2; GnomAD popmax AF = 0.0000121 — very rare for unknown gene (threshold 0.001) — PM2 moderate.
BP4
Computational evidence supports benign — no pathogenic computational or splicing signal (BP4); Splicing verdict: benign (Strong).; Germline computational verdict: benign (Moderate).
BP7
Synonymous variant at non-conserved position with no predicted splicing impact (BP7); Synonymous at non-conserved position, no splicing concern — benign (BP7).
