Impairment of tRNA processing by point mutations in mitochondrial tRNALeu(UUR) associated with mitochondrial diseases

Abstract

Several point mutations in mitochondrial tRNA genes have been linked to distinct clinical subgroups of mitochondrial diseases. A particularly large number of different mutations is found in the tRNA(Leu)(UUR) gene. We show that base substitutions at nucleotide position 3256, 3260, and 3271 of the mitochondrial genome, located in the D and anticodon stem of this tRNA, and mutation 3243 changing a base involved in a tertiary interaction, significantly impair the processing of the tRNA precursor in vitro. In correlation with other studies, our results suggest that inefficient processing of certain mutant variants of mitochondrial tRNA(Leu)(UUR) is a primary molecular impairment leading to mitochondrial dysfunction and consequently to disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
