2. What is chromosomal aberration CNV
What is chromosomal aberration CNV? The embryo exhibits abnormal cell division. Most of the chromosomal aberrations (CNV) have little to do with the genetics of the parents, but they may cause fetal organ abnormalities and even fetal malformations. It is best to do a chromosomal abnormality screening during pregnancy. Once fetal malformations occur, timely treatment When terminating a pregnancy, you must maintain a good attitude.
3. How to treat if the woman has chromosomal abnormalities

At the beginning, I didn’t know anything but I was looking around for treatment methods. Later I learned that it could only be blocked through third-generation test tube technology. Just after the third generation of pregnancy, a pair of twins, a boy and a girl, were born. You can consult more.
4. What are chromosomal diseases
Chromosome diseases include autosomal Genetic diseases and sex chromosome genetic diseases. Humans have 22 pairs of autosomes and 1 pair of sex chromosomes. Genetic diseases caused by an abnormal number of autosomal chromosomes include trisomy 21, trisomy 13, trisomy 18, meowing syndrome, etc. Genetic diseases caused by autosomal structural abnormalities include balanced chromosome translocations, Roche translocations, etc. Sex chromosome disorders include Turner syndrome and Creutzfeldt-Jacob syndrome. 47, XXX. Super X syndrome. 47, XYY. Super Y syndrome, fragile X syndrome, etc.
5. What are the causes of chromosomal abnormalities
What are the causes of chromosomal abnormalities? It may be due to the older age of the pregnant woman or the influence of external environmental factors that cause chromosomal abnormalities. During pregnancy preparation, if both or one of the spouses works in a place with high radiation, you can temporarily give up work, or you can take some folic acid tablets. , the folic acid in folic acid tablets can also prevent fetal malformations.
6. Can I have a fetus with chromosomal abnormalities
Depends Different situations. Whether the fetus can be preserved mainly depends on the severity of the fetal chromosomal abnormality and whether the ultrasound indicators are abnormal. If the chromosomal abnormality is only mild, it will have no impact on the fetus and can be preserved. And if the chromosomal abnormality is very serious, such as the presence of trisomy 21 or obvious microdeletions and microduplications, it will have an impact on the fetus, so the fetus cannot be retained.
This ends the introduction about chromosomal abnormalities and the causes of chromosomal abnormalities. I hope it will be helpful to everyone.
