The epidemiology of Turner syndrome

The epidemiology of Turner syndrome is largely unknown. A few studies of prevalence and incidence of the syndrome have been performed based on large chromosome surveys, and based on these studies it may be estimated that Turner syndrome occur in 50 per 100,000 liveborn females. A considerable delay in diagnosis of new cases of Turner syndrome exists in all studied populations, emphasizing clinical vigilance, and some are only diagnosed upon reaching adulthood. Based on available data morbidity is increased due to a number of conditions and diseases. As a result mortality is also increased. Better care and medical treatment of females with Turner syndrome will likely reduce the increased morbidity and mortality.
