title: [Satellite association in two trisomic cases of Down's syndrome and in one healthy mother, with acrocentric variants (author's transl)].
abstract: The frequency of satellite association of two different acrocentric variants in two trisomic mongols was studied taking in consideration the possible relationship of these chromosomes in the etiology of non-disjunction events. The participation of the two variants and their homologous in satellite associations showed no differences suggesting, randommess in these two families.
