MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This nuclear gene encodes a mitochondrial protein which belongs to the FRATAXIN family. The protein functions in regulating mitochondrial iron transport and respiration. The expansion of intronic trinucleotide repeat GAA from 8-33 repeats to >90 repeats results in Friedreich ataxia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2016]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit early post-implantation lethality, in the absence of intramitochondrial iron accumulation. Conditional knockouts, specific to striated muscle and neuron/striated muscle, show cardiac hypertrophy and large sensory neuron dysfunction, respectively. [provided by MGI curators]
