Chromosomal microarray analysis accurately detects abnormalities in individual chromosomes

Two years and more than 2,000 samples after researchers at Baylor College of Medicine started to use a new gene-chip technology called chromosomal microarray analysis to look for potential genetic abnormalities in children, they find that it is remarkably sensitive in detecting abnormalities in individual chromosomes, according to a report that appears online today in the journal Public Library of Science ONE.
