Abstract
Partial trisomy 18 is described in a 2 mo. old female with severe mental, motor and growth retardation, associated with multiple congenital anomalies characteristic of complete trisomy 18. Trisomy for almost all of 18q resulted from adjacent I segregation of a paternally inherited translocation t(13;18)(q32;q11). The balanced translocation was observed in 3 generations of the family. Partial trisomy 18q identical to that observed in the proband was found in a subsequent miscarriage.
