How to stop the inheritance of progressive muscular dystrophy: 1, first of all, the patient needs to be tested for DMD gene, clear gene mutation loci and types. 2, if the patient’s mother is a carrier of the mutation gene, the need to collect amniotic fluid or umbilical cord blood for prenatal diagnosis, if the fetus disease will need to terminate the pregnancy. 3. If the mother does not carry the mutation, it is recommended that prenatal diagnosis of amniotic fluid or umbilical cord blood be done because of the fear that the mother may have gonadal chimerism, i.e., the mother’s blood test is normal, but the mutation may be present in the egg, and the mutation in the egg will still be passed on to the offspring. 4, Other women in the family may also be carriers of the mutation gene, so it is necessary to take precautions when giving birth. 5. The time for prenatal diagnosis is usually 16-20 weeks for amniotic fluid collection and 20-24 weeks for umbilical cord blood collection. 6, prenatal diagnosis method is: DMD gene test + chain analysis. 7, if the patient has not detected the gene mutation, women in the family can only be prenatal diagnosis by chain analysis method, but the accuracy will be affected. 8.If the patient is deceased, DMD gene testing can be done on her mother to try to find the disease-causing mutation to accurately guide the re-birth.
