Cancer Chromosome Microarray
Single nucleotide polymorphism (SNP) chromosome microarray (CMA) is a molecular cytogenomic technology that evaluates areas of the human genome for gains or losses of chromosome segments at a higher resolution than traditional karyotyping. Due to the small size, many of these DNA imbalances may not be detected by standard cytogenetics. SNP CMA also will identify marker chromosomes, some cases of mosaicism, and aneuploidy.
The performance characteristics of this test, including sensitivity and specificity, have been determined by Genetics Associates. All results are interpreted by board certified and Tennessee licensed cytogenetic directors at our laboratory, who are available to discuss results and offer clinical advice.
