WebCytogenetics is the analysis of chromosomes as they relate to constitutional genetic disease and acquired cancer-related genomic abnormality. Constitutional genetic applications include pre-and post-natal diagnosis of genetic syndromes such as Down syndrome and investigation of causes of reproductive failure. WebComprehensive constitutional cytogenetics testing can be performed on a variety of tissue types, including amniotic fluid, chorionic villi, bone marrow, blood, products of conception, and skin biopsies. Our standard is a complete chromosome analysis augmented by appropriate FISH probes, and/or chromosome microarray.
