Partial deletion of the X chromosome in gonadal dysgenesis 46,X,del(X)(p22) identified by BUdR treatment

Abstract
In this report we describe a deletion of the short arm of the X chromosome in a 16-year-old female with gonadal dysgenesis. The breakpoint was localized by BUdR treatment and acridine orange staining in region 2, band 2. Of the examined cells, 3% showed an early replication of the deleted X chromosome.
