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 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.914

The c.590C>T (p.P197L) alteration is located in exon 5 (coding exon 5) of the TRUB1 gene. This alteration results from a C to T substitution at nucleotide position 590, causing the proline (P) at amino acid position 197 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
