Clinical Significance
Chromosomal microarray (CMA) detects aneuploidies, deletions and duplications below the resolution of chromosome analysis (karyotyping), and long continuous regions of homozygosity. Approximately 50% of first trimester pregnancy losses are due to chromosome abnormalities. While chromosome analysis on products of conception has an increased failure rate, chromosomal microarray is a DNA-based analysis, which rarely has assay failures.
