The Cytogenetics Laboratory studies chromosome morphology. In conjunction with the Molecular Genetics Laboratory, microarray testing is also offered to further evaluation the genetic constitution of children with clinical disorders. The Cytogenetics Laboratory also processes specimens for the study of hematologic and soft tissue malignancies. In addition to the morphologic evaluation of chromosomes, the lab also performs the molecular cytogenetic technique of fluorescence in situ hybridization (FISH). FISH analysis allows for the identification of specific chromosome abnormalities that are beyond the resolution of a standard morphologic evaluation. The laboratory also serves as a cell culture facility for specimens that need specialized (non-cytogenetic) testing.
