Turner's syndrome

Abstract

Summary

Before chromosomal analysis became available, the diagnosis of Turner's syndrome was based on the characteristics independently described by Otto Ullrich and Henry Turner, such as short stature, gonadal dysgenesis, typical, visible dysmorphic stigmata, and abnormalities in organs, which present in individuals with a female phenotype. Today, Turner's syndrome or Ullrich-Turner's syndrome may be defined as the combination of characteristic physical features and complete or part absence of one of the X chromosomes, frequently accompanied by cell-line mosaicism. The increasing interest in Turner's syndrome over the past two decades has been motivated both by the quest for a model by which the multi-faceted features of this disorder can be understood, and the endeavour to provide life-long support to the patient. New developments in research allow patients with Turner's syndrome to have multidisciplinary care.
