Patient's question:
Hello, I had a chromosome karyotype analysis after an amniocentesis. The test result report shows 320-400 bands, G-banded level analysis: 46, XN, iv(9)(p11q13). Could you please explain what each of these means?Doctor's answer:
Analysis of the condition: Since I cannot tell you the gender of the fetus, it can only be represented as 46, XN. 46, XY is the normal karyotype for males, and 46, XX is the normal karyotype for females. iv(9)(p11q13) indicates a translocation between the short arm 1 region 1 band and the long arm 1 region 3 band of chromosome 9.Advice: Since I cannot tell you the gender of the fetus, it can only be represented as 46, XN. 46, XY is the normal karyotype for males, and 46, XX is the normal karyotype for females. iv(9)(p11q13) indicates a translocation between the short arm 1 region 1 band and the long arm 1 region 3 band of chromosome 9.
