A case of t(1;21) in a 9-year-old female Down syndrome patient is reported. Her karyotype was 47, XX, t(1;21) (mat), +21. The father's karyotype was normal, while that of the mother was 46, XX, t(1;21). An amniotic fluid cell culture revealed a trisomy 21 and a t(1;21) in a male fetus. This is the first report of a familial case of trisomy 21 with t(1;21) from our country.
