The present work was aimed at generating the dynamic standard reference intervals (DSRI) and their application for chromosomal-aberration (CA) analysis. The evaluation of the generated DSRI was performed using the DNA samples from four patients with already known CA. High-resolution comparative genomic hybridization analysis (HR-CGH) allowed us to not only identify all of the CAs, that were not revealed by CGH, but also to detect the breakpoints and to determine the size of chromosomal imbalance.
