The CMA process involves several steps: 1. Sample Collection: A small blood or tissue sample is collected from the newborn. 2. DNA Extraction: DNA is extracted from the collected sample. 3. Labeling and Hybridization: The DNA is labeled with fluorescent dyes and hybridized onto a microarray chip. 4. Scanning and Analysis: The chip is scanned, and the data is analyzed to identify any chromosomal abnormalities. 5. Interpretation: Geneticists interpret the results, often using databases of known CNVs and their associated conditions.
