Premature Centromere Division Dominantly Inherited in a Subfertile Family
Overview

An increased frequency of mitoses showing premature centromere division (PCD) in every chromosome was found in lymphocyte cultures from four members of a subfertile family. These cells were observed in both the presence and absence of colchicine. Cultured fibroblasts from the proband showed only normal diploid metaphases. PCD cells seemed to have a shorter cell cycle. The anomaly was transmitted in a way compatible with autosomal dominant inheritance in this family.
