Chromosomal deletion or duplication syndromes result from deletion or duplication of parts of chromosomes. They may cause severe congenital anomalies and significant intellectual and physical
disabilities. Vista™ Chromosome Sequencing uses NGS based low coverage whole genome sequencing (WGS) to help detect chromosome abnormalities before or during pregnancy.

The results obtained from testing can reduce a patient’s emotional burden and information from the results can improve the chances of a future successful pregnancy. If the chromosome abnormality in the fetus is identified as causing the pregnancy loss, parents can usually be reassured that the chance of recurrence is low, and avoid a costly medical check-up.
