(1) Wheeler et al., 1988 [15]6 pregnancies, 3 term, 1 premature delivered infants, 1 termination, 1 intrauterine death: 4 healthy children, 2 fetuses normal on autopsy
Domain I:
100% normal
Domain II:
100% no mental retardation
Domain III:
100% Normal reproductive fertility and normal genitalia
9 children with abnormal intern/extern genitalia, 7 children with ambiguous genitalia at birth, 2 children with primary amenorrhea at age 17
Domain I:
22% short stature, webbed neck
Domain II:
100% no mental retardation
