Mice are viable although lifespan is severely reduced. An under-representation of mutant males suggests some prenatal lethality. Generalized and progressive myopathy starts at around 4 weeks of age with amyotrophy and accumulation of central nuclei in skeletal muscle fibers, leading to death at 6-14 weeks. Mutants also show mitochondrial disorganization and increased levels of desmin with abnormal desmin intermediate filament formation and architecture. {ECO:0000269|PubMed:12391329, ECO:0000269|PubMed:21135508}. |
