A conversation between husband and wife Wife: The next-door neighbor did not go to the prenatal examination in order to save money, and now they are about to give birth to detect that the baby may have a genetic defect (progressive muscular dystrophy), which will lead to the patient's hand and foot muscle disorders, severe patients can not take care of themselves, may not be able to walk and stand and run like a normal child for a lifetime. Now the heart is full of sorrow, the family has no laughter, and sighs every day. Now the family is immersed in the confusion of the future, and they do not know how to comfort. Looking at the children conceived by healthy couples will actually have genetic defects!
Husband: Men have one X chromosome and one Y chromosome, and females have two X chromosomes. This means that the disease is common in men because they have only one X chromosome, and if the X chromosome goes wrong, there is no other option for muscle fibers. Then the woman has a defect in the X chromosome gene. The other may still be functioning normally. Because the onset is associated with the X chromosome, it is also known as X-linked recessive inheritance. Other words. Men suffer from muscular dystrophy. Symptoms are revealed from an early age. The chromosomes in the body have been inactivated, or defective. Muscle fibers cannot function into the body if a woman has muscular dystrophy. Symptoms are hardly apparent. There is another X-stain in the body. That is, the other half of the anti-amyotrophin genes are still functioning. It is recommended that couples who are preparing to have a baby do a genetic test. To prevent occult muscular dystrophy. Diseases such as muscular dystrophy can be detected by amniocentesis at 16 to 18 weeks of pregnancy. Amniocentesis is mainly suitable for expectant mothers over the age of 35 and 15 to 18 weeks pregnant. If there is a family history of genetic disorders or chromosomal abnormalities, and the test finds abnormalities, doctors will recommend a diagnosis of amniocentesis. Women with muscular dystrophy need to be tested accordingly during pregnancy preparation and early pregnancy.
