Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_014817.4(TRIL):​c.2188C>T​(p.Arg730Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000301 in 1,397,480 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R730Q) has been classified as Uncertain significance.

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=0.24128988).

The c.2188C>T (p.R730W) 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 2188, causing the arginine (R) at amino acid position 730 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
