Chromosome aberrations contribute significantly to human disease. Close collaboration between our clinical and research cytogenetics laboratories contributes to a better understanding of specific chromosome regions and chromosome abnormalities, in particular, their structure, origin, segregation, stability, contribution to fetal development and survival, and impact on clinical genetics, including cancer. In collaboration with other laboratories at OHSU, we have a specific focus on the molecular biology of Fanconi anemia, a recessive disorder of DNA repair which has the classic finding of chromosome instability. Investigation of all of the above areas requires utilization of the following state-of-the-art tools: high resolution chromosomes, multiple staining techniques, breakage analysis, sister chromatid exchange assays, metaphase and interphase fluorescent in situ hybridization (FISH) and array comparative genomic hybridization.
