Why can't chromosomal abnormalities be cured?

summary

My husband's friend got married the year before last and had a baby last year. Some time ago, my husband told me that their children had chromosome abnormalities. Because we planned to have a child in two years, we asked our husband for their details. I hope my friends can learn from it. Now let's share the prevention and treatment of chromosomal abnormalities.

Why can't chromosomal abnormalities be cured?

First, many genetic diseases are not detected until the child is born because they are not checked before pregnancy, but it is too late, causing unnecessary pain to parents and children. Modern medicine has been very developed, some genetic diseases can be prevented by chromosome examination. There are many ways to check chromosomes. Chromosome banding technique is to stain human chromosomes with quinacrine first, and then show a series of horizontal stripes with different width and position on each chromosome. After different treatments such as heat, alkali, salt and enzyme, a series of horizontal stripes with different colors are shown, which is called chromosome banding. It can help us to distinguish the chromosome defects and improve the recognition ability.

Second: at present, the treatment is mainly symptom therapy and organ deformity correction, and gene therapy, cell therapy and replacement therapy are also developing. Gene transfer technology: gene therapy generally adopts three gene strategies: replacement, correction and supplement. At the present level of treatment, it is impossible to replace and correct mutant genes. The feasible strategy is to transfer normal genes to the cells of patients with genetic diseases through a certain vector, so as to achieve the purpose of treatment. This is called gene transfer technology.

Third: the mother should eat a light diet, eat more fruits and vegetables, match the diet reasonably, and pay attention to adequate nutrition. It's better for children to have adequate breast milk.

matters needing attention

The treatment of chromosomal dysplasia is difficult and the curative effect is not satisfactory, so the prevention is particularly important. Preventive measures include premarital examination, genetic counseling, chromosome testing, prenatal diagnosis, if there is a risk of giving birth to children, selective abortion and other measures to prevent the birth of children.
