| Type | disruption phenotype | Description | Mice display a high mortality rate, both during embryogenesis and after birth, germ cell failure and sterility. Mutant females exhibit ovarian dysgenesis and lack ovarian follicles at reproductive maturity. Affected males have small testes due to arrest of spermatogenesis during meiotic prophase I. Early chromosome pairing appears normal but synapsis occurs between sister chromatids rather than between homologous chromosomes. |
