在国内做第三代试管婴儿可以筛选基因不得糖尿病吗？
Genetic screening, including screening for diabetes-related mutations, is possible with third-generation IVF technology in this country, but it does not completely prevent diabetes. PGD technology can detect chromosome number and structural abnormalities in embryos, as well as mutations in certain single-gene diseases. However, for complex diseases, such as diabetes, where there is an interaction of multiple genes and environmental factors, it is still not possible to completely eliminate the risk of diabetes through genetic screening.
Doctor's Perspective:
Diabetes is a common chronic disease caused by high blood sugar and is usually caused by congenital genetics or multiple environmental factors. IVF can test for a number of potential genetic disorders, including diabetes. The test can determine the presence of diabetes risk genes in the fertilized eggs, thus helping patients to better understand their genetic status and to take effective preventive measures in advance.
Third-generation IVF uses pre-implantation genetic diagnosis (PGD) to screen for healthy embryos for transfer to the mother, and because of the screening of embryos, this avoids the possibility of genetic diseases, but diabetes is not part of the category of genetic diseases, and is not inherited per se, the focus is on the susceptibility to diabetes, and even if the children of diabetic patients also have diabetes, that is inherited susceptibility to disease Even if the children of a diabetic have diabetes, they have inherited a predisposition to the disease. Simply put, the children of a diabetic have inherited certain genes that make them susceptible to diabetes.
