Abstract
Pregnant women are offered a biochemical screening test for Down syndrome in the second trimester, where the suspicion for SLOS could be registered, when the unconjugated estriol (uE3) level appears low. A group of 456 fetuses with a high risk for SLOS were examined by DNA analysis. We confirmed SLOS in 5 fetuses and 11 fetuses were carriers.Both of them had nonsense mutation on one allele. It stands to reason that some modifying factors may play a role in the reduction of the uE3 level in the mother's serum.
Abstract (in Czech)
Na našem pracovišti byla provedena DNA analýza DHCR7 genu u vzorků plodů s podezřením na Smith-Lemli-Opitzův syndrom, které jsme obdrželi na základě druhotrimestrálního biochemického screeningu těhotných žen, ve kterém byla prokázána snížená hladina uE3. Nízká hladina nekonjugovaného estriolu (uE3) v těchto případech značí zvýšené riziko Smith-Lemli-Opitzova syndromu (SLOS). Z výsledků vyplynulo, že druhotrimestrální biochemický screening zachytí s jistotou hlavně těžce postižené plody.
