Comparison of cytogenetics and molecular karyotyping for chromosome testing of miscarriage specimens

Cytogenetics, single-nucleotide polymorphisms, and array comparative genomic hybridization/short-tandem repeat markers are all acceptable options for detecting chromosome imbalances in miscarriage specimens. We detected an unexpected high rate of mosaicism.

Abstract:

This study demonstrates the many technical limitations of the three testing modalities. Our rates of maternal cell contamination were low, but it is important to note that this is a commonly reported limitation of cytogenetics. Given the similar overall performance of the three testing modalities, providers may choose a method based on individual availability and consideration of limitations as it applies to each clinical scenario. The unexpected high rate of placental mosaicism warrants further investigation.
