Looking at chromosomes

Karen Marks, senior clinical scientist in cytogenetics, discusses the impact that array CGH (Array Comparative Genomic Hybridization) has had on clinical practice.

Karen describes the process of array CGH, where a patient’s DNA sample is compared against the reference DNA, that is considered to have no abnormalities. She also explains how to spot the imbalances in patients’ DNA.
