Variants pathogenicity by type
Statistics on ClinVar variants can assist in determining whether a specific variant type in the TRMT5 gene is commonly pathogenic or not.
In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.
Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

- Function
- FUNCTION: Involved in mitochondrial tRNA methylation (PubMed:26189817). Specifically methylates the N1 position of guanosine-37 in various tRNAs. Methylation is not dependent on the nature of the nucleoside 5' of the target nucleoside. This is the first step in the biosynthesis of wybutosine (yW), a modified base adjacent to the anticodon of tRNAs and required for accurate decoding. {ECO:0000269|PubMed:26189817}.;
- Disease
- DISEASE: Combined oxidative phosphorylation deficiency 26 (COXPD26) [MIM:616539]: A mitochondrial disorder characterized by lactic acidosis, multiple mitochondrial respiratory-chain-complex deficiencies in skeletal muscle, and additional variable features including hypertrophic cardiomyopathy, exercise intolerance, and failure to thrive. {ECO:0000269|PubMed:26189817}. Note=The disease is caused by mutations affecting the gene represented in this entry.;
- Pathway
- Synthesis of wybutosine at G37 of tRNA(Phe);tRNA modification in the nucleus and cytosol;tRNA processing;Metabolism of RNA
