Mice homozygous for disruptions in this gene die in mid-gestation. Structural and functional abnormalities of mitochondria are reported. Mice homozygous for a conditional allele in male germ cells exhibit small testes with abnormal sperm flagellum, aggregation of mitochondria, and disrupted male meiosis.
