Fetal Structural Anomalies clinical trials at University of California Health

This study follows an observational prospective cohort design. Women with fetal structural anomalies are routinely offered diagnostic testing with chorionic villus sampling or amniocentesis, with analysis for chromosomal analysis using karyotype or microarray analysis. Women in whom such testing does not explain the fetal phenotype, or in whom a genetic disease is strongly suggested based on the phenotype or a pattern of recurrent anomalies, will be offered exome sequencing (ES) and/or genome sequencing (GS) through the UCSF CLIA certified Genomic Medicine Laboratory. In advance of study enrollment, patients have been counseled regarding the structural anomalies in the fetus and offered pregnancy termination. The sequencing results for on-going pregnancies have a turnaround time of 2-4 weeks, and in the majority of cases are available after decisions have been made regarding continuation or termination of pregnancy. Patients who decline diagnostic testing but who have a prenatally identified anomaly may be offered the option of testing on umbilical cord blood at delivery or on the placenta or other products of conception after a stillbirth or pregnancy termination. The project is exploratory in nature, with the ultimate goal of contributing to a growing body of phenotypic data and understanding how providers and patients utilize genomic (either exome or genome) sequencing results during pregnancy.
