A balanced insertion of a parent may produce normal or carrier offsprings, spontaneous abortions, and chromosomally unbalanced offsprings. This is a rare report of duplication of chromosome 10q22->q24 which has arisen through the segregation of a balanced direct insertion. The partial trisomy 10q is a specific syndrome of mental retardation and malformation characterized by psychomotor delay, growth restriction, distinctive dysmorphic appearances, and, in some cases, cardiac, renal, and ocular abnormalities. We have experienced a case of partial trisomy 10q from maternal balanced insertion, which was prenatally showed severe fetal growth restriction and oligohydramnios, and present it with a brief review of literatures.
Key Words: Partial trisomy 10q, Balanced insertion
