Mitochondrial disease v0.1058 MT-TP Zornitza Stark edited their review of gene: MT-TP: Added comment: DEFINITIVE by ClinGen.

At least 9 individuals reported. Age of onset of affected individual is variable. Clinical features reported include myopathy, chronic progressive external ophthalmoplegia (CPEO), retinal dystrophy, and lactic acidosis. Muscle biopsy often shows classic findings of mitochondrial myopathy with COX-negative and ragged red fibers. Respiratory chain enzyme deficiencies may also be observed in muscle biopsies. The pathogenic variants were present at high levels of heteroplasmy in muscle tissue and, frequently, other tissues such as blood, saliva, buccal samples, urine, and fibroblasts harbored the variant at substantially lower heteroplasmy levels, including being undetectable. Affected individuals have been reported with heteroplasmy levels as low as 25-40% in muscle tissue. Single fiber studies were performed in several probands further supporting variant pathogenicity.; Changed publications: 7689388, 11196116, 19223931, 23696415, 19273760, 27536729, 27816331, 32305257, 32419253; Changed phenotypes: Mitochondrial disease (MONDO:0044970), MT-TP-related
