Genes affected

TRIL (HGNC:22200): (TLR4 interactor with leucine rich repeats) TRIL is a component of the TLR4 (MIM 603030) complex and is induced in a number of cell types by lipopolysaccharide (LPS) (Carpenter et al., 2009 [PubMed 19710467]).[supplied by OMIM, Apr 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.28895885).

The c.2237G>A (p.R746Q) alteration is located in exon 1 (coding exon 1) of the TRIL gene. This alteration results from a G to A substitution at nucleotide position 2237, causing the arginine (R) at amino acid position 746 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
