Genes affected

TRUB1 (HGNC:16060): (TruB pseudouridine synthase family member 1) Pseudouridine is an abundant component of rRNAs and tRNAs and is enzymatically generated by isomerization of uridine by pseudouridine synthase (Zucchini et al., 2003 [PubMed 12736709]).[supplied by OMIM, Mar 2008]

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=0.11474994).

Ambry Genetics

Jan 02, 2024

The c.67G>C (p.E23Q) alteration is located in exon 1 (coding exon 1) of the TRUB1 gene. This alteration results from a G to C substitution at nucleotide position 67, causing the glutamic acid (E) at amino acid position 23 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
