    An 18-year-old female with some stigmata of pure dysgenesis had a chromosome constitution of 46,X,dir dup(X) (pter leads to q27: :q21 leads to qter). The abnormal chromosome was always late replicating. The clinical and cytogenetic picture is compared with that of patients with X;X translocation and some problems of karyotype-phenotype correlation are discussed.
