Flow chart for the new diagnostic approach to patients with mental retardation. *If the CNV exceeds 200 kb, we recommend additional FISH analysis to confirm the CNV in the patient and screen for balanced translocations or insertions in the parents. If the CNV is smaller than 200 kb, we recommend a second array analysis on the patient to confirm the CNV and on the parents to test heritability.
