Mitochondrial disease v0.1026 MT-ND4L Zornitza Stark edited their review of gene: MT-ND4L: Added comment: LIMITED by ClinGen.

Seven probands with m.10063T>C have been reported across five publications, all of whom had LHON. These cases were scored with reduced points by ClinGen given the mild impact this variant has been shown to have on complex I function. While three other missense variants (m.10543A>G, m.10591T>G, m.10680G>A) have been reported, the ClinGen Expert Panel agreed there was only sufficient evidence of pathogenicity for the m.10663T>C variant. Cases with m.10680G>A and m.10543A>G and m.10591T>G were reviewed but excluded from scoring due to a lack of compelling functional evidence to support pathogenicity. The m.10543A>G variant has been modeled in E. coli and showed a very mild reduction in NADH dehydrogenase activity (74% of control), which was not sufficient to be included in scoring.; Changed rating: AMBER; Changed publications: 8680405, 11935318, 17003408, 22879922, 24568867; Changed phenotypes: Mitochondrial disease (MONDO:0044970), MT-ND4L-related
Mitochondrial disease v0.1026 MT-ND4 Zornitza Stark Phenotypes for gene: MT-ND4 were changed from Mitochondrial complex I deficiency; Leber's optic neuropathy; Dystonia to Mitochondrial disease (MONDO:0044970), MT-ND4-related

Mitochondrial disease v0.1024 MT-ND4 Zornitza Stark commented on gene: MT-ND4: DEFINITIVE by ClinGen.

Multiple individuals reported presenting with a broad phenotypic spectrum of clinical features including Leber Hereditary Optic Neuropathy (LHON); mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS); LSS; cerebellar ataxia, migraines, regression, developmental delay, leukoencephalopathy, myoclonus, seizures, stroke-like episodes, cognitive decline, psychiatric illness, Parkinsonism, axonal neuropathy, multiple sclerosis, ophthalmoplegia, short stature, and hypertrophic cardiomyopathy. Age of onset varied from infancy to adulthood. Muscle biopsy showed COX-negative fibers and complex I deficiency.

Heteroplasmy levels in affected individuals ranged from 60% - 83% in muscle, 40% - 80% in blood, and 76% - 78% in myoblasts, as well as from 57% - 73% in various other tissues (fibroblasts, liver, urine, buccal). Of note, the m.11778G>A common LHON variant was reported in affected individuals in the homoplasmic and heteroplasmic states.
