What is the mortality rate for turner syndrome?

In the absence of serious problems such as cardiovascular and renal defects or hypertension, or if the problems are successfully treated, the life span of an individual with Turner syndrome is expected to be normal (Buyse, 1990).

The annual report for the birth defects registry in Hawaii reported the first-year mortality rate for Turner syndrome to be 5.3% (Merz and Forrester, 2000). One investigation reported that the Infant Mortality Rate associated with all sex chromosome abnormalities increased during 1985-1997
