Reagents, Molecular Assay, Chromosome Anomaly, Trisomy

Definition : Molecular assay reagents intended for use in identifying the presence of three homologous chromosomes rather than the normal two (i.e., trisomy) in a patient sample. Congenital trisomies are typically characterized by physical and developmental disorders (e.g., trisomy in chromosome 21 is known as Down syndrome); acquired trisomies are usually the result of malignancy, tumors, and/or other disorders (e.g., trisomy in chromosome 12 is associated with chronic lymphocytic leukemia). Some individuals show mosaicism, a condition in which normal and three-chromosome cells are present in the same person.
