What are the benefits of Cytogenetic Microarray testing?
This testing allows us to look at over 150 specific microdeletion / duplication syndrome regions, subtelomeric regions, and locations throughout the genome at one time. Early studies suggest 8-10% of patients with normal chromosome results may have an abnormality that can be detected with microarray testing. This is higher than the detection rate found with subtelomere analysis following chromosome testing. Microarray testing will allow for diagnosis of these known disorders in fetuses, children, and adults with less obvious features of these conditions. SNP microarray testing may enable the diagnosis of chromosomal imbalances which have been previously described in children and adults with your patient’s features. This may allow physicians to anticipate medical needs of those patients and direct their care more appropriately once a diagnosis has been made.
