Satellite associations and silver staining in a case of multiple G and D variants

Satellite associations and silver staining were analyzed in a normal woman carrying three "s" variants, on chromosomes 13, 21, and 22. Six of the acrocentric chromosomes were identified and a positive correlation between the parameters of satellite association frequency and positive silver staining was found for each chromosome. These parameters seem to depend on the presence and size of a secondary constriction and are unaffected by stallelite size.
