Outcome Measures

Primary Outcomes (1)

  • Number of signs of Turner syndrome

    Girls diagnosed with Turner syndrome by fetal ascertainment will have more signs of Turner syndrome than girls diagnosed by maternal ascertainment

    three to six years

Secondary Outcomes (1)

  • Growth

    three to six years

Study Arms (2)

Fetal ascertainment

Girls who are diagnosed with Turner syndrome because of concerns raised by an abnormal fetal ultrasound.

Maternal ascertainment

Girls who are diagnosed with Turner syndrome because their mothers had an amniocentesis for a reason other than an abnormal fetal ultrasound concerning for Turner syndrome. For example an amniocentesis was done because of advanced maternal age or because of an abnormal triple screen or because another condition was being screened for such as trisomy 21.
