| **Homoplasmy** | \- | **Heteroplasmy** | \+ | **mitoTIP** | 72\.30% | **Pathogenicity** | Reported \[VUS] |

"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.

# **Pedigree Information**

The **m.10406G\>A** variant in MT\-TR has been reported in 1 pedigree. To date, 1 carrier has been reported. Reported mutation loads ranged from 0% to 96%, with a median of 32\.5% overall; affected carriers showed mutation loads from 0% to 96%, with a median of 32\.5%. In one affected carrier, the mutation was undetectable in other tissue (0%) but exceeded 20% in blood (29%), muscle (96%), urine (94%), and bone marrow (36%). The main clinical manifestations among affected carriers included asperger syndrome, mitochondrial myopathy, bilateral ankle equinus contractures, occasional dysphagia, progressive muscle weakness, and proximal limb weakness.
