# **General Information**

| **Position** | **5843** | **Variant** | **m.5843A\>G** | **Locus** | **MT\-TY** | **RNA** | **tRNA Tyr** |
| --- | --- | --- | --- | --- | --- | --- | --- |
| **Homoplasmy** | \+ | **Heteroplasmy** | \- | **mitoTIP** | 8\.40% | **Pathogenicity** | Reported |

"Pathogenicity" status is derived from published literature or predictions from bioinformatics tools. Researchers and clinicians are cautioned that additional data and/or analysis may still be necessary to confirm the pathological significance of these variants.
