- This publication demonstrated the potential clinical utility of detecting chromosome anomalies other than the common aneuploidies using Expanded NIPT. In this study population, 1.6% of the cases undergoing Expanded NIPT were screen positive for a rare chromosome anomaly that was either a rare autosomal trisomy or a large partial deletion/duplication. Of these cases, 60% were associated with an adverse pregnancy outcome, including abnormal fetal phenotype and intrauterine growth restriction.
