[The Shereshevskii--Turner syndrome in monozygotic twins].

The authors present data on the clinico-cytogenetic, roentgenological, hormonal and anthropometric examination of monozygotic twins with the Shereshevsky-Turner syndrome. Mosaicism (45,X/46,XX) was revealed in both sisters, but the correlation of normal and anomalous cellular clones proved to differ. There was a great similarity between the twins, the size of their body, signs of dermatogliphics and odontology; however somatic features of the Shereshevsky-Turner syndrome and sexual insufficiency with a more pronounced increase in gonadotropins and phenomena of the CNS irritation were revealed in the patient with the prevalence of anomalous 45,X clone.
