It is understood that some of the parents' genes will be passed on to their children. Of course, these genes are good and they are bad. Which genes in parents can be passed on to their children? The characteristics of parents can be transmitted to children through the genetic material in the body, so that children in the form, character and physiology show a place similar to the parents, which is called genetic. However, some parents have defects in their genetic material (genes), which is transmitted to their offspring to produce children with genetic diseases. At present, although more and more genetic diseases have been discovered and some treatments have been found, there are many genetic diseases that still make people helpless. Therefore, prevention is particularly important. How to avoid genetic disease minefield? Genetic disease is a disease in which a parent’s genetic material (gene) is transmitted vertically between the parent and offspring in a certain manner. Without this genetic gene, it cannot cause disease. Genetic disease is characterized by life-long illness and familial disease. Usually, it is manifested when the child is born, such as congenital ignorance, multi-fingered, etc., but there are some that show up after a certain period of growth and development, such as muscular dystrophy to childhood disease, baldness The onset of the disease is only after the age of 30. Some genetic diseases have a certain relationship with environmental factors. For example, the height of a person is determined by a genetic gene, but if nutrition and exercise are strengthened after birth, the child may be higher than their parents. If they are hemophilia, if they are guarded, To avoid trauma, there will be no symptoms of bleeding; as galactosemia, it must be in the milk that contains lactose before it will develop. Explain the risk of genetic diseases Autosomal recessive genetic disease This is an autosomal inherited disease, often manifested as albinism, phenylketonuria, galactosemia, dementia, dementia, glycogenosis, sputum type, mucopolysaccharide disease, liver bean Nucleus degeneration and so on, the genetic pattern is characterized by: 1. The patient's parents are often disease-free, but they are carriers of the disease-causing genes. 2. It is not distributed continuously, that is, it is not passed from generation to generation. It is distributed. 3. In the case of close relatives, the incidence of recessive genetic diseases in children is much higher than that of non-close relatives. Autosomal dominant genetic disease is an autosomal hereditary disease, often manifested as multiple fingers (toes), finger (toe), achondroplasia, incomplete osteogenesis, spherocytosis, thalassemia, etc. : 1. One of the patient's parents must have this disease. 2. There are consecutive generations of this disease, which is passed from generation to generation. 3. If the parents are not sick, the children are generally not affected. Genetic risk prediction: These patients are mostly heterozygous, if the spouse is sick, the child's incidence probability is 1/2; if both are heterozygous patients, the incidence of children is 3/4; if both spouses are pure In zygote patients, all children are affected. Genetic risk prediction: If the patient is homozygous, their parents are often normal, but a child born with a second child may have a 25% risk of recurrence; if the spouse is sick and the other is completely normal, the child is not a disease but is a causative gene. Carriers; if one spouse is sick and the other is a carrier of the disease-causing gene, one-half of the children are born and one-half is the carrier of the gene. When Mom and Dad learn more about the history of their family and their families, they are also learning more about our future baby. Let's open the door to a more exciting life with our baby.
