Can a person with abnormal chromosomes in their first child still have a second child?

Patient's question:

In 2007, I gave birth to a boy naturally, who was light in weight. At that time, a chromosomal balanced translocation was detected during the examination. Now he is two years old, and there are no intellectual issues. Some of his movements are slightly slower than those of his peers, but his appearance is clearly different from other children—wide-set eyes, small eyes, and a high forehead. May I ask if I can apply for a second child? What is the likelihood of success?

Doctor's answer:

Analysis of the condition: The child appears generally without deformities and intelligence is not affected. In such a case, it is best for both parents to undergo a chromosomal test. If there is confirmation of an issue, it should be possible to apply for a second child.
Advice: Chromosomal abnormalities are not necessarily inherited by every child. It also depends on the specific details of the chromosomal abnormality.
