Abstract: | In the first child of this family, the diagnosis of male pseudo-hermaphroditism due to 17 keto-reductase deficiency was established at two months of age after HCG test. During the second pregnancy, amniocentesis was performed for fetal karyotype and steroid determination in the amniotic fluid: an affected male fetus was suspected and this prediction was confirmed at birth. For the third pregnancy, a prenatal diagnosis was requested again and made, according to the same procedure: a normal male fetus was predicted and this diagnosis was confirmed at birth; this study demonstrates the feasibility and reliability of a prenatal diagnosis for 17 keto-reductase deficiency. |
