Patient's question:
My girlfriend's uncle is mentally disabled, while her parents are mentally sound. However, her brother is also mentally disabled. If we get married and have children, is there a possibility that they could inherit the mental disability from her uncle or brother?Doctor's answer:
Hello, it is hereditary, but it is a matter of probability. If it is a hereditary intellectual defect, it is related to many genes, and many gene or chromosomal defects can cause this disease. However, if the mother has a defect and the father is normal, it is still possible to have normal offspring. The same applies in reverse. It is recommended to consult a genetic counselor at the hospital. Otherwise, it is not a solution for generations to pass down this condition.
