Inactivation of the Friedreich ataxia mouse gene leads to early embryonic lethality without iron accumulation
Abstract
Friedreich ataxia (FRDA), the most common autosomal recessive ataxia, is caused in almost all cases by homozygous intronic expansions resulting in the loss of frataxin, a mitochondrial protein conserved through evolution, and involved in mitochondrial iron homeostasis. Yeast knockout models, and histological and biochemical data from patient heart biopsies or autopsies indicate that the frataxin defect causes a specific iron-sulfur protein deficiency and mitochondrial iron accumulation leading to the pathological changes. Affected human tissues are rarely available to further examine this hypothesis. To study the mechanism of the disease, we generated a mouse model by deletion of exon 4 leading to inactivation of the Frda gene product. We show that homozygous deletions cause embryonic lethality a few days after implantation, demonstrating an important role for frataxin during early development. These results suggest that the milder phenotype in humans is due to residual frataxin expression associated with the expansion mutations. Surprisingly, in the frataxin knockout mouse, no iron accumulation was observed during embryonic resorption, suggesting that cell death could be due to a mechanism independent of iron accumulation.

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.
