✦ Synopsis

Fetuses with degenerative neurological disorders or metabolic diseases rarely exhibit sonographic abnormalities. As a result, prenatal diagnosis, when available, requires invasive testing. Prenatal diagnosis of spinal muscular atrophy (SMA) can be made by testing chorionic villi or amniocytes. Indirect genotype analysis by use of single-and multi-locus polymorphic microsatellites of the region 5q11.2-q13.3 is used. We present two cases of SMA that manifested at 11 and 16 weeks' gestation by the presence of abnormal ultrasound findings. Each case also had abnormal maternal serum screening. 1997 by John Wiley & Sons, Ltd.

In a study of amniotic fluid from 91 Down syndrome cases and 240 controls, we have shown that the median value of CA125 in pregnancies affected by Down syndrome on the whole reflects those observed in the maternal serum from 106 affected cases and 238 controls. The median MOM for CA125 in amniotic f
