Chromosomal microarray analysis (CMA) provides comprehensive genetic testing for the most common chromosomal conditions as well as a large number of severe genetic conditions not detected by traditional chromosome analysis. This test explores chromosomes in detail to help detect genetic conditions that cause significant disabilities. Baylor Genetics evaluates the entire human genome for regions that contain too many or too few copies of genetic material.
Baylor Genetics provides two postnatal CMA options: CMA – High-resolution (HR) + Single Nucleotide Polymorphism (SNP) Screen and CMA – HR. When we receive your patient’s sample, it is analyzed against a control to determine differences in copy number variations (deletions or duplications). The location and type of change will often dictate the cause of your patient’s health condition.
CMA is highly recognized as a first-tier diagnostic test in the pediatric setting and should be considered for individuals who lack a sufficient specific history or features on physical examination to suggest a specific genetic (or non-genetic) cause for intellectual disability, developmental delay, autism spectrum disorder, or multiple congenital anomalies.
