Nettet10 timer siden · They have examined mtDNA in induced pluripotent stem cells derived from patients with Leigh syndrome or neuropathy, ataxia or retinitis pigmentosa (NARP). This has revealed complex patterns of pathogenic mtDNA mutations, including single nucleotide variants and large structural variants. Mutations in mitochondrial DNA (mtDNA) and over 30 genes in nuclear DNA (gene SURF1 and some COX assembly factors) have been implicated in Leigh disease. Disorders of oxidative phosphorylation, the process by which cells produce their main energy source of adenosine triphosphate (ATP), may be caused by mutations in either mtDNA or in nuclear encoded genes.
