RESUMO
A child with characteristic clinical features of Down's syndrome and raised red cell SOD-1 activity was found to have, in addition to a single chromosome 21, a reverse dicentric tandem translocation of two No 21s with dual NORs and C band regions. The breakpoints on the chromosomes involved in the translocation were at the most distal end of the long arms (21q223). The phenotypically normal mother carried a rare variant of a chromosome 9.
