| Outline of Final Research Achievements |
PLK-4 is a key regulator of centriole duplication and male mice with a point mutation in Plk4 are known to show azoospermia associated with germ cell loss. We found a heterozygous 13-bp deletion of PLK4 in an azoospermic patient with Sertoli cell-only syndrome (SCOS). In vitro centriole amplification was observed in wild-type PLK4-transfected cells, but not in mutant ones, indicating that the PLK4 mutation can cause azoospermia by SCOS.
