The karyotypes were obtained from 200 cases who had been referred for suspected chromosomal abnormalities to cytogenetic laboratory in Soonchunhyang University Hospital from January. 1987 to June. 1989.
Out of 200 cases, 36 cases had the abnormal karotypes and the others had normal karyotypes. Among the 36 chromosomal anomalies, there were the autosomal anomalies in 14 cases(38.9%), the sex chromosomal anomlies in 10 cases(27.8%) and normal autosomal variation in 12 cases(33.3%).
The results were obtained as follows:
1. Autosomal anomalies
1) 21 trisomy 7 cases
2) 18 trisomy 2 cases
3) Philadelphia chromosome 1 case
4) 45, XX, t(14q 21q) 2 cases
5) 46, XX, t(7:15)(q36:23) 2 cases
2. Sex chromosomal anomalies
1) 47, XXY 1 case
2) 45, X/ 46, XY 1 case
3) 45, X 2 cases
4) 45, X/ 46, Xi(Xq) 2 cases
5) 46, X,i(Xq) 1 case
6) T. F. Syndrome 2 cases
7) del(X)(q25) 1 case
3. Normal Autosomal variation
1) inv 9(p11 q21) 5 cases
2) 1 qh+ 1 case
3) 13 p+ 2 cases
4) 14 p+ 2 cases
5) 22 p+ 2 cases
