Abstract

Mice that are deficient in either the Pms2 or Msh2 DNA mismatch repair genes have microsatellite instability and a predisposition to tumours. Interestingly, Pms2-deficient males display sterility associated with abnormal chromosome pairing in meiosis. Here mice deficient in another mismatch repair gene, MIh1, possess not only microsatellite instability but are also infertile (both males and females). MIh1-deficient spermatocytes exhibit high levels of prematurely separated chromosomes and arrest in first division meiosis. We also show that MIh1 appears to localize to sites of crossing over on meiotic chromosomes. Together these findings suggest that MIh1 is involved in DNA mismatch repair and meiotic crossing over.
