title: New mutation causing sterility in the mouse.
abstract: A new murine mutation, skeletal fusions with sterility, sks, has been identified. This mutation causes arrest during the pachytene stage of virtually all spermatogenic cells. Defects in chromosome pairing and appearance of the synaptonemal complex during meiosis in the male are apparent, but defective pairing is probably not the cause of sterility. Affected females are functionally infertile. Oocytes are capable of undergoing meiotic maturation in vitro but cannot be fertilized in vitro. Affected individuals of both sexes are characterized by fusions of vertebrae and of ribs. The sks gene has been mapped to Chromosome 4, 16.6 cM distal to the brown locus.
