Is diabetes an autosomal recessive or dominant disorder?

The main characteristics of diabetes are polydipsia, polyuria, polyphagia, of course, it has a lot to do with certain genetic factors, and now the diabetic population has accounted for 1/10 of the total population, so when you feel that you have these characteristics, you should start to prevent it, I heard that Okinawa, Japan's "clear sugar yoshi" prevention or ** diabetes is very good!

Deficiencies in the autoimmune system.

Heredity generally refers to the phenomenon that the traits of the parents are represented below, and genetics, specifically refers to the phenomenon of genetic material being passed from the previous generation to the offspring, which is a common phenomenon in the biological world. The baby will look like his parents, because the parents' appearance, physiology, personality, physique, etc. are inherited to the baby. Heredity is divided into dominant inheritance and recessive inheritance.

The so-called dominant inheritance means that only one dominant gene needs to be carried in a pair of genes, and it does not need to be a pair, and its determined traits will be manifested, such as cephalic rotation and double eyelids.

The so-called recessive inheritance means that the genes that determine the performance of traits must exist in pairs, otherwise the traits affected by a single gene will only be hidden, such as small eyes and straight hair.

Complkete dominance is when a heterozygous (AA) patient exhibits an identical phenotype as a dominant homozygous (AA) patient. According to Mendel's law of segregation, the two A's of genotype Aa must be one from the father and one from the mother.

Brachydactyly, for example, is an autosomal complete dominant malformation in which the fingers (or toes) become shorter or absent due to the shortness or absence of the phalanges. Assuming that the gene that determines brachydactyly is dominant gene A and normal digit is recessive gene A, the genotype of a patient with brachydactyly should be AA or AA.

It is only possible to have a child with type AA when both parents are patients with brachydactyly, and the vast majority of patients with brachydactyly have AA. If the patient (AA) marries a normal person (AA), 1 2 of the children born to him are patients, that is, for every child born, there is a 1 2 chance that he will have brachydactyly.

Recessive inheritance is when one of two healthy people is sick. The pathogenic gene is recessively represented by A, and only AA individuals will be infected dominantly, that is, those who are sick may be able to give birth to healthy, and those who are not sick will never give birth to disease. The pathogenic gene is dominantly denoted by A, and both AA and AA will get sick.

Recessive inheritance refers to the fact that the parents carry a certain gene, but do not develop the disease, and his gene is passed on to the offspring to make it sick, such as autosomal recessive polycystic kidney disease, which is the case with the previous generation, but there is no manifestation of polycystic kidney disease in life, and its offspring develop this gene through inheritance, and show very serious symptoms in birth and infancy, and some even in the fetal period. For example, red-green color blindness, hemophilia, albinism, etc. Dominant genetic disease (AA or AA) means that the disease is determined by the dominant gene A, that is, as long as there is a A, it is dominant, AA, AA are both diseased, and AA has no disease-causing gene and will not be diseased.

In layman's terms, dominant inheritance is generational onset, and recessive inheritance is intergenerational onset.

Dominant inheritance on the X chromosome.

There are more females than males in the patients;

continuous inheritance; If a man is sick, his mother and daughter must be sick;

The females are normal, and their fathers and sons are all normal;

Women have at least one parent who has the disease.

The so-called recessive inheritance refers to the fact that the parents carry a certain gene but do not develop the disease, and the gene is passed on to the offspring to cause the disease. This is the case with autosomal recessive polycystic kidney disease, in which the previous generation carries this gene but does not show signs of polycystic kidney disease throughout life, and the offspring inherit the gene and then develop the disease, and show severe symptoms at birth and in infancy (and some even in the fetal period). Such as red-green color blindness, hemophilia, albinism.

Genetic diseases can be autosomal dominant diseases, so what are the characteristics of autosomal dominant diseases?

Autosomal dominant inheritance is characterized by the fact that if the parents have children with hereditary diseases, there will be the possibility of rapid disease, and it is not affected by gender, the probability of male and female diseases is equal, there are many types of autosomal dominant genetic diseases, such as polydactyly or glaucoma and ovarian cysts or muscle atrophy, etc., if the parents have a hereditary disease, and the children do not have diseases, there will generally be no genetic conditions after marrying a normal person.

Specifically, if the parents are sick, the chances of the child being sick are the same, regardless of gender. If one parent is sick and the other parent is normal, the chance of the child getting sick is usually 50%. If both parents are sick, the chance of a child getting sick is usually 75%.

When a child is sick, one of the parents must be sick. If the parents have a disease and the child is normal, it means that the child does not carry the disease-causing gene and will not pass the disease-causing gene to his offspring.

An autosomal dominant disorder is one in which the disease-causing gene is located on the autosome. There are autosomal dominant diseases that can be seen, because they have characteristics, so what are the characteristics of autosomal dominant diseases?

Because such diseases are passed down from generation to generation, the onset of the disease has nothing to do with gender, and the male and female grandchildren have an equal chance of getting the disease, if the patient marries a normal person, the children born 1 2 may be sick, so it should be forbidden to have children. Autosomal dominant genetic diseases include skeletal hypoplasia, osteogenesis imperfecta, Marfan syndrome, primary epilepsy, retinoblastoma, multiple fluid familial colon polyposis, congenital myotosis, progressive muscular dystrophy, etc.

Common autosomal dominant diseases are seen more in life, which is also called congenital achondroplasia, which is dominantly inherited, that is, patients with dwarfism have children, and the risk of developing the disease is 50%. Half of all children also show symptoms of dwarfism, which is characteristic of autosomal dominant disorders.
