title: [A review of the data from cytogenetic and molecular cytogenetic research on human supernumerary minichromosomes].
abstract: The literature about the nature of marker chromosomes (mini-chromosomes of unknown origin) in patients with mental retardation, hereditary defects of development as well as in healthy individuals is reviewed. The advantage of the use of modern molecular methods of research for the analysis of nature and origin of additional mini-chromosomes is demonstrated.
