Brief cytogenetic report on maternal translocation t(7;9)(p22:p23): Two sibs with duplication 9p and one sib with the balanced translocation

Abstract
We report on a family in which a maternal translocation (7;9) (7qter → 7p22::9p13 → 9pter; 9qter → 9p13) resulted in 2 sibs with dup(9p) syndrome, one sib with the same balanced constitution as the mother, and one normal boy.
