Patient's question:
I have been divorced from my husband for over two years now, and we are now planning to have a child. Therefore, we went to the hospital for pre-pregnancy tests. The detailed examination results showed that there was a recurrence of abnormality in my 9th chromosome. The doctor said that this is very likely to be passed on to the baby. I would like to ask what are the possible causes of the 9th chromosome abnormality?Doctor's answer:
The human body has a total of 23 pairs of chromosomes. The first 22 pairs are autosomes, and the 23rd pair is the sex chromosome, which determines the gender of the baby. If there is an abnormal phenomenon in the human body's chromosome 9 again, it is very likely caused by long-term exposure to ionizing radiation or a toxic working environment. It could also be due to intergenerational genetic factors. Since it has been discovered that there is an abnormal phenomenon in one's own chromosomes, it is necessary to implement targeted treatment.
