MADISON, Wis.--(BUSINESS WIRE)--High-resolution comparative genomic hybridization (CGH) has rapidly emerged as the method of choice for molecular cytogenetic detection and characterization of chromosomal abnormalities associated with mental retardation, cancer, and other complex phenotypes. In two recent studies published in the Journal of Medical Genetics (1, 2), high-resolution NimbleGen CGH arrays were used to further characterize two recently identified genomic disorders (3, 4).
