Molecular cytogenetics combines two disciplines, molecular biology and cytogenetics, and involves the analyzation of chromosome structure to help distinguish normal and cancer-causing cells. The field is overall focused on studying the evolution of chromosomes, more specifically the number, structure, function, and origin of chromosome abnormalities. It includes a series of techniques referred to as fluorescence in situ hybridization, or FISH, in which DNA probes are labeled with different colored fluorescent tags to visualize one or more specific regions of the genome. In our clinic we provide genetic tests for detecting diseases that are impossible to be detected by chromosome analysis or examine the genetic abnormalities which are not fully and precisely defined via chromosome analysis.
