Genetic markers of hereditary diseases

Over the past 30 to 40 years, conventional karyotyping has been the gold standard test for detecting chromosomal abnormalities.
A method has recently emerged that allows us to go much further in the study of chromosomes; it is called Comparative Genomic Hybridization, or array-CGH.
