The pathogenicity scoring system for mitochondrial tRNA mutations revisited
Confirming the pathogenicity of mitochondrial tRNA point mutations is one of the classical challenges in the field of mitochondrial medicine. In addition to genetic and functional studies, the evaluation of a genetic change using a pathogenicity scoring system is extremely useful to discriminate between disease-causing mutations from neutral polymorphisms. The pathogenicity scoring system is ve...
متن کاملMitochondrial DNA Mutations, Pathogenicity and Inheritance
Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...
متن کاملmutational analysis of mitochondrial trna genes in patients with asthma
background: mitochondria are autonomous cellular organelles that oversee a variety of functions such as metabolism, energy production, calcium buffering, and cell fate determination. most recently, mitochondrial dysfunction caused by mitochondrial mutations played important roles in the pathogenesis of asthma. however, the frequency of mitochondrial trna mutations in asthma is largely unknown. ...
متن کاملThe role of mitochondrial tRNA mutations in lung cancer.
Alternations in mitochondrial genome resulting in mitochondrial dysfunction have long been hypothesized to be involved in tumorigenesis. Mitochondrial tRNA (mt-tRNA) is known for its high frequencies of polymorphisms and mutations, however, the roles of these mutations and polymorphisms in lung cancer are among heated debates. To evaluate the possible roles of reported mt-tRNA mutations in lung...
متن کاملthe point mutations of mitochondrial trna threonine and proline in idiopathic repeated pregnancy loss
background: mitochondrial transfer rnas (trna) genes are essential components of protein biosynthesis. these genes are hotspots for mutations. these mutations are associated with a wide spectrum of human disease. many genetic factors are known in assessment of repeated pregnancy loss (rpl). objective: the aim of this study was analysis of trna thr and trna pro in women with rpl. materials and m...
