MT-TV
geneOn this page
Also known as trnV
Summary
MT-TV (mitochondrially encoded tRNA-Val (GUN), HGNC:7500) is a mitochondrial tRNA gene on chromosome mitochondria.
At a glance
- Gene type: non-coding (Mt_tRNA) — no protein product; not a drug target. Variant/disease associations are omitted (they would be positional, from an overlapping protein-coding gene).

Literature-anchored findings (GeneRIF, showing 2)
- Variations in the levels of mitochondrial valyl tRNA synthetase between tissue types and patients may underlie the difference in clinical presentation between individuals homoplasmic for the 1624C>T MTTV (equivalent to mt-tRNAVal C25U) mutation. (PMID:18400783)
- study describe 4 patients with the m.1644G>A in the MT-TV gene; the mutation appeared to have a steep threshold effect with asymptomatic life up to 70% mutation proportion, progressive encephalopathy above 80% and severe Leigh-like syndrome above 95% mutation (PMID:24691472)
