Regarding genetic diseases, what are genetic diseases?

Yes, congenital heart disease, but it doesn't have to be 19 years old.

They generally live up to their twenties.

Genetic diseases refer to the changes in the genetic material of people, resulting in a class of diseases The genetic material mainly includes chromosomes and genes, so hereditary diseases can be roughly divided into chromosomal diseases, genetic diseases, single set diseases and polygenic diseases. A chromosomal disorder is a disease caused by a change in the number or structure of chromosomes. For example, Down syndrome.

Monogenic diseases are a type of disease caused by genetic mutations and changes in genetic material, such as congenital color blindness, deafness, hemophilia, etc. Polygenic diseases are a type of disease caused by two or more gene mutations and environmental factors, such as congenital heart disease.

As the name suggests, a genetic disease is a disease caused by a change in the structure or function of the genetic material. It is usually congenital, but it can also be acquired.

Genetic diseases are diseases caused by mutations in genes. Because genes are hereditary, it is possible to pass on the disease to the next generation. If the mutation occurs in a recessive gene, recessive inheritance occurs, that is, the patient may not have specific symptoms, but may cause the next generation to develop lesions.

If the mutation occurs in the dominant gene, if no symptoms occur in the next generation, the offspring will no longer be hereditary.

It is a congenital disease caused by changes in the genetic material of the next generation due to genetic or other factors. They are called genetic diseases.

A genetic disease is a disease that occurs in a parent, such as hepatitis. Hepatitis will be passed on to children, and children will be passed on to their children, which is called a genetic disease?

It's a disease that your older generation had, and the next generation has the same disease, which is a genetic disease.

A genetic disorder is a genetic defect in the parent's inherited disease.

Genetic material mainly includes chromosomes and genes, so genetic diseases can be divided into chromosomal disorders, monogenic disorders, and polygenic disorders.

Down syndrome.

Down syndrome, also known as trisomy 21, is a typical genetic disorder that usually manifests as mental retardation, unusual appearance, and malformations in growth and development, which are caused by chromosomal abnormalities. In general, people with Down syndrome only have a genetic effect on their immediate family members, which means that if one of the parents has Down syndrome, the child is more likely to develop the disease than normal.

Thalassemia.

Thalassemia is a genetically defective disorder in which people are often born with dysplasia, rarely survive to adulthood, and even if they survive, they need long-term blood transfusions or bone marrow transplants. In general, when both spouses have mild thalassemia, their children will have a high chance of developing severe thalassemia.

AlbinismAlbinism is a genetic disorder that usually manifests as a deficiency of melanin in the appendages, resulting in a white or yellowish-white appearance of the eyebrows, hair, and other body hairs. Albinism runs in families and is an autosomal recessive disorder that often occurs in people who are consanguineously married.

HemophiliaHemophilia is an inherited bleeding disorder of blood clotting disorders that is inherited through sex chromosomes. Usually presents with unexplained bleeding throughout the body that is difficult to stop for a long time. However, the genetic demand conditions for hemophilia are high, so the heritability of hemophilia is not high.

What diseases will be passed on to the next generation.

1. Allergies and asthma are hereditary diseases, and children are the ones with the highest incidence. If parents have asthma or parents who have allergies to pollen, dust, etc., their children are likely to inherit it. If one person is sick, the chance of the child being inherited is 30%-50%, and if both parents are sick, the chance of the child being inherited is 80%.

2. Parents with high blood pressure and blood lipids will also inherit their children, generally if one of the parents is sick, the probability of inheritance of the children is 50%, if both parents suffer from this disease, the probability of the child being inherited will reach 75%.

3. Obesity, if one parent is severely obese, the child has a 40% chance of being inherited, and if both parents are obese, the probability of the child being inherited may reach 70%.

How to reduce disease genetics.

1. Choose a good time to conceive. The age of both spouses should be appropriate. If a woman is over 35 years old, the chance of her offspring suffering from congenital stupidity can increase by about 10 times; It is advisable for the man to be no older than 40 years old.

2. Pay attention to the "external environment" of both men and women when they are conceived, and avoid the harmful external environment for a period of time before they want to conceive.

3. If the woman has a miscarriage less than half a year after the miscarriage, do not conceive immediately; If more than two spontaneous miscarriages occur in a row, a chromosomal test should be done to determine whether genetic factors are involved, and the doctor will decide whether to conceive again.

Hepatitis B. Hepatitis B is inherited. I don't know anything else.

Monogenic genetic diseases (also divided into dominant and recessive genetic diseases), polygenic genetic diseases, and chromosomal diseases.

Is it inherited from one generation to the next generation if there is a deformity of hands and feet in the womb?
