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 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.1987328).

Jul 09, 2021

The c.2284T>A (p.F762I) alteration is located in exon 1 (coding exon 1) of the TRIL gene. This alteration results from a T to A substitution at nucleotide position 2284, causing the phenylalanine (F) at amino acid position 762 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
