Genes exist within the body's proteins, and IVF, because of its rigorous testing, generally does not have genetic mutations, but does not rule out acquired factors. Can IVF rule out genetic mutations?
Can IVF rule out genetic mutationsGenetic mutations refer to diseases or abnormalities caused by changes in genes during the formation of the embryo. It is currently believed that genetic diseases caused by genetic mutations are untreatable, because genes are missing, misplaced or increased in the chromosomes of the embryo, causing abnormalities in the growth of cells throughout the body. However, because of the existence of third-generation IVF technology, for single-gene disease caused by genetic mutations, can be preimplantation testing of embryos to rule out the inheritance of disease-causing genes in the offspring.
Autosomal dominant disorders: Autosomal dominant disorders include skeletal dysplasia, osteogenesis imperfecta, scleral syndrome, retinoblastoma, multiple familial colon polyps, melanoma, gastrointestinal polyposis, congenital myasthenia gravis, etc. The dominant gene for these disorders is located on the autosomes, so that the same disease may occur in every generation of the patient's family, and the disease is not related to gender. The disease has nothing to do with sex, both men and women can develop the disease, and the risk rate of the children born to the patient and normal people is 50%, so it is not suitable for childbearing. X-linked dominant genetic diseases: Because the dominant gene of the patient is on the X chromosome, there are more females than males in the patient, and the offspring of the female patient, no matter whether it is a son or a daughter, have a risk of developing the disease of 50% of the same disease, so it is not suitable for childbearing, and the offspring of the male patient, 100% of the daughters have the same disease, so it is not suitable for childbearing. X-linked recessive genetic diseases: These genetic diseases are commonly found in hemophilia A, hemophilia B and progressive muscular dystrophy. Because the recessive genetic diseases are located on the Y chromosome, most of the patients are males, and when a male patient marries a normal female, all the boys born are normal, but all the girls are carriers of the disease-causing genes. If a female carrier marries a normal male, the son has a 50% risk of developing the disease, and the child is normal.
How long can a baby live with a genetic mutationThe genes in the human body exist in very high content, each person has the possibility of genetic mutation, some of the human body obviously expresses the abnormality of the disease state, and some people just appear some changes, and even some may make the human body better, not that the genetic mutation will not be able to survive. Many people may not have any physical harm, there are only changes, such as human beings before the existence of lactose intolerance, the gene mutation may produce lactase in the human body, so that when you drink milk will no longer appear lactose intolerance phenomenon.
Some people used to have brown eyes, and after the gene mutation, some people's eyes became blue eyes, although blue eyes do not have too much impact on the overall vision of the human body, but it can make the human appearance more beautiful, so the gene mutation will not produce certain diseases, or even if it produces certain diseases does not necessarily immediately appear to be the death of a person, according to the specific gene mutation caused by the symptoms, and then decide on the health of the body. The symptoms are judged according to the specific gene mutation after the cause of the symptoms, and then decide the degree of impact on the body.
