Why do children get metabolic diseases?

If our body's metabolic function is abnormal, we are particularly prone to stagnation, vomiting, and anemia. These are closely related to our metabolism, and the speed of metabolism also has a great impact on these. However, the factors that generally determine the speed of metabolism are not only related to genetics, but also to lifestyle habits. So why do children suffer from metabolic diseases?

Genetic metabolic disease is a genetic disease with defective metabolic function. Genetic diseases also have causes. Its symptoms are usually mental retardation, anemia, vomiting, diarrhea, etc. During my internship, I saw some common knowledge about the disease in a medical book. I have some understanding of this disease, and I will share it with you below. I hope that you can also understand it and then help those in need.

experience:

Anyone who has studied biology knows that people inherit through the genes in their chromosomes. Some people don't want to read about this because they don't understand it. It’s actually not as difficult as you think. Simply put: There are 23 pairs (46) chromosomes in human cells. Of these, 22 pairs are the same in both males and females and are called autosomes; the other pair is the sex chromosomes. There are two types of sex chromosomes, X chromosomes and Y chromosomes. Females have XX chromosomes and males have XY chromosomes. The disease-causing gene can be present on an autosome or on the X or Y chromosome. The normal chromosomes become abnormal.

Autosomal (recessive) inheritance. That is, the diseased gene is on the (auto) chromosome, and the genetic trait is recessive, that is, the children will only show symptoms when there are problems with the genes provided by both parents. For this genetic disease, both parents are carriers of the disease-causing gene, and there is a one-in-four chance that the child will be sick, with boys and girls having an equal chance of getting sick. There is a one in two chance that a child will become a carrier of the disease gene and a one in four chance that the child will be a normal child.

Autosomal (dominant) inheritance is similar to autosomal (recessive) inheritance, that is, the disease gene is on the autosome, the gene trait is dominant, and if both parents are sick, the child born will be sick.

Sex-linked (recessive) inheritance. That is, a lesion appears on X. Most of the babies born are boys who suffer from the disease, while girls rarely suffer from this disease.

X-linked (dominant) genetic disease. It is a disease caused by a dominant gene located on the X chromosome. Whether it is a boy or a girl, as long as the disease-causing gene is present, the disease will occur. However, because women have two X chromosomes, the incidence rate of women is about twice that of men. Because there is no normal chromosome to mask the disease, men tend to have more severe symptoms than women.
