Added comment: LIMITED by ClinGen.

There were 3 scoreable probands across >10 publications from 1996-2022. Notably, while cybrid analyses were performed (PMID:36039763), one of the variants, m.5783G>A, was excluded from scoring for three reasons: 1.) the reported phenotype of isolated hearing loss was non-specific and incompletely penetrant, but also 2.) the biochemical impact in cybrids was mild - moderate, and 3.) there was reduction in expression of mitochondrial replication genes (TWNK ~30% of control in cybrids) suggesting an alternative aetiology might be responsible for the biochemical impact reported.

The gene-disease association for MT-TC is also supported by the known interaction with a multitude of other mitochondrial translation proteins (PMID:30030363) and respiratory chain studies and Northern blot analysis supporting MT-TC dysfunction leading to Complex I deficiency (PMID:35252560).
