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 Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.049749285).

The c.1691C>T (p.A564V) alteration is located in exon 1 (coding exon 1) of the TRIL gene. This alteration results from a C to T substitution at nucleotide position 1691, causing the alanine (A) at amino acid position 564 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
