Overview
Epidemiology
- Turner syndrome occurs in 1 of 2500 live births. [1]
- 45 XO is the most common karyotype followed by mosaicism.
- Studies have shown that 30 percent of the time, Turner syndrome remains undiagnosed till adolescence. Therefore, it’s true prevalence cannot be estimated. "Turner Syndrome - StatPearls - NCBI Bookshelf".
- The prenatal prevalence is much higher than the postnatal prevalence and the intrauterine mortality rate is higher when compared to the patients of the same age.
- Turner syndrome patients have a higher mortality rate when compared to the general population. [2]
- Approximately 98% of all fetuses with Turner syndrome spontaneously abort. Turner syndrome accounts for about 10% of the total number of spontaneous abortions in the United States.
