[Trisomy of chromosome No. 10 in mosaic (author's transl)].
A case of trisomy of chromosome No. 10 in mosaic is described in a boy who died at the age of 6 months. The frequency of pathological cells is less than 30% (28% from lymphocytes, 20% from fibroblasts); it is possible, anyway, to rule out the hypothesis of a cellular cloning in vitro, since the trisomy 10 was observed in two different cultures, terminated after 48 and 72 hours. The parents' karyotype was normal, except for a litte number (6%) of cells with trisomy 10 from cultured lymphocytes of the mother. The morphological features of the present case are compared with those of the boy described by Higurashi et al. in 1969 (mosaic of trisomy 10, with a higher frequency of pathological cells).
