Patient's question:
I recently had a miscarriage check-up on the embryonic villous tissue and found a deletion in chromosome 17. Both parents' chromosomes are normal. Is this related to genetics? Is this abnormality the reason for the miscarriage? In this case, what abnormal manifestations would the child have if born? What kind of treatment is available? Medical history: recurrent miscarriageDoctor's answer:
Hello, if either party in a couple has a chromosomal abnormality, the chances of giving birth to a normal offspring under normal conception conditions are very low. It is very easy for miscarriages, stillbirths, and malformed fetuses to occur. Even if a child is born, the probability that the offspring will have a normal appearance but still carry a chromosomal abnormal karyotype (i.e., phenotypically normal in genetics) is only 1/9. Moreover, such offspring will also face the same problems as their parents when they reach reproductive age. The issues caused by this genetic defect cannot be resolved through medication.
