geneOn this page
Also known as trnD
Summary
MT-TD (mitochondrially encoded tRNA-Asp (GAU/C), HGNC:7478) 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).
