PubMed 38855161 · doi:10.3389/fcell.2024.1410245
What was done
Narrative review synthesizing molecular pathways of mitochondrial protein synthesis, human disorders arising from translation defects (including nuclear-encoded translation factors, mitoribosomal proteins, and aminoacyl-tRNA synthetases), and corresponding animal models.
What was found
The abstract gives no numerical findings or statistical measures. It describes that advances in cryo-electron microscopy and next-generation sequencing have expanded the identification of genes and structural components required for mitochondrial translation, and notes that resulting pathologies are typically multisystemic with neurodegenerative phenotypes in high-energy tissues.
Why it matters
This review synthesizes the molecular genetics of mitochondrial translation machinery and maps how translation failures drive multisystem human mitochondrial diseases.
Limits
The abstract reports no original experimental or clinical data, provides no quantitative synthesis, and does not describe a systematic literature search. Sample sizes and specific frequencies of mutations are not reported.
