Mitochondrial disease v0.1075 MT-TY Zornitza Stark edited their review of gene: MT-TY: Added comment: DEFINITIVE by ClinGen.

Multiple individuals reported. Age of onset in affected individuals is variable and clinical features seen include myopathy with or without ophthalmoplegia. There is at least one case report with a more severe phenotype with neuropathy, ataxia, seizures, myoclonus, sensorineural hearing loss, and pigmentary retinopathy. Muscle biopsy in affected individuals has shown COX-negative and ragged red fibers, with variable mitochondrial respiratory chain enzyme deficiencies. The variants in affected individuals are often present at highest heteroplasmy levels in muscle and may be undetectable in other tissues such as blood and buccal tissue. Multiple single fiber studies were performed in these patients and supportive of variant pathogenicity; Changed publications: 11071502, 11756614, 11594340, 33279411, 30643656, 32684384, 32485333, 33279411; Changed phenotypes: Mitochondrial disease (MONDO:0044970), MT-TY-related
