title: [Value of silver staining technics for the study of acrocentric ring chromosomes and supernumerary microchromosomes].
abstract: The silver staining techniques was used to study two cases of ring chromosomes (ring chromosome 15 and ring chromosome 22) and two cases of small extra chromosomes. This technique allows identification of the breakpoints and provides some information about the origin of small extra chromosomes.
