Genomic DNA variance:

The GFC has performed array-based comparative genomic hybridization (aCGH) using the Agilent aCGH Bioarrays. The GFC recognized the limitations of interpreting aCGH data in isolation and initiated a no-cost collaboration with the karyometry lab at the University of Arizona Health Sciences Center. Pairing a karyotype with aCGH, particularly when the reference cells are non-diploid, provides greatly improved data interpretation for investigators.
