Klinefelter’s Syndrome in Prenatal Diagnosis: Incidence and Consequences for Genetic Counselling
Prenatal diagnosis offers the possibility of ascertaining distinct genetic defects through the analysis of fetal cells obtained by amniocentesis. The amniotic fluid is withdrawn in the 16th or 17th gestational week through a transabdominal tap. The fetal cells in the sample are cultivated over 2 weeks and chromosomal preparations (or metabolic tests) are performed using standard methods.
