Status:Active, not recruiting
The main objective of this multi-center collaborative study is to evaluate the accuracy, efficacy and clinical advantages of prenatal diagnosis using array-based copy number (microarray) analysis as compared with conventional cytogenetic (CC) analysis using microscopy.
Women will be approached for recruitment at the time of their scheduled amniocentesis or CVS. In the case of amniocentesis - a small amount of additional fluid will be drawn for microarray analysis. In the case of CVS procedure - no additional chorionic villi will be collected (anything not needed for clinical analysis will be used). The standard testing will be performed. In addition, microarray analysis will be performed and compared with the standard results.
Some children will undergo developmental tests up through 24 months, based on the agreement between the clinical test and microarray testing.
