[2 cases of trisomy 11q(q231--qter) by translocation t(11;22) (q231;q111) in 2 different families].

Two cases of partial trisomy 11q are reported, both apparently due to segregation in both patients' families of the same translocation between a n degrees 11 and a n degrees 22. R-, T-, and G- banding showed the breakage points to be 11q231 and 22q111. The clinical syndrome results from trisomy for the q231 leads to qter segment of chromosome 11.
