Pregnant at 24 weeks, the amniocentesis results show trisomy 4 on the long arm of chromosome 4.

Patient's question:

It was done at Harbin Red Cross Women's and Children's Hospital.

Doctor's answer:

To see what genetic information this gene carries, if it is not important genetic information, it may not have a significant impact. If the repeated segment carries important genetic information, it is very likely to cause abnormalities.
