Various genetic disorders that can not be prevented

Genetic disorders are diseases that are characterized by changes in the nature and component of the genes responsible for the disease. This condition can be caused by new mutations in DNA or by abnormalities in genes inherited from parents.
Genetic disorders can cause a variety of conditions, ranging from physical or mental disabilities or disorders to certain diseases, such as cancer. Even in this case, not all cancers are caused by genetic disorders. Some may also be due to environmental factors and poor lifestyle.

Various genetic disorders

Here are some genetic disorders that we often hear:

color blind

Color blindness is a genetic disorder that may be familiar. Usually, the human eye has three types of cone cells that react at different wavelengths of light. To be able to see color, pigments from these three types of cones must work well. If not, there will be color blindness.
There are two main types of color blindness. The first type is partial (partial) color blindness, which is difficult to distinguish between blue and yellow, or only green and red. While the second type is total daltonism, also called achromatopsia.

Sickle cell

This genetic disease is caused by genetic errors which then affect the development of red blood cells. Red blood cells with this disease have an unusual shape, which prevents them from living as long as healthy blood cells in general.
Sickle cell disease can be a problem because it traps blood cells in blood vessels. Children with this disease from birth may suffer from anemia, be susceptible to infection, and become sick in some parts of the body. Even in this case, there are also patients who have only a few symptoms and can live normally.

blood disease

Hemophilia is a group of blood disorders that occur from generation to generation. This genetic disease is caused by an error in one of the X chromosome genes, which determines how the body makes blood clotting factors. This condition prevents blood from clotting normally, so that when a patient suffers an injury or injury, the bleeding that occurs will be longer.

Klinefelter's syndrome

Is a genetic disease that only occurs in humans. Patients with Klinefelter syndrome have symptoms in the form of a small penis and testicles, hair only grows slightly on the body, has large breasts, smaller and less proportional. Other features of this genetic disease are lack of testosterone and infertility.

Down Syndrome (Down syndrome)

Down syndrome is caused by an excess of genetic material in children, which inhibits the physical and mental development of children.
Usually, a person gets 23 chromosomes from a father and 23 chromosomes from a mother with a total of 46 chromosomes. In Down syndrome, genetic disorders occur when the number of chromosomes 21 increases, so the total chromosomes obtained by children is 47 chromosomes.
This condition cannot be avoided because it is a genetic disorder, but can be detected earlier before the birth of a child. The condition of children with Down syndrome may be different from each other. Some children can live reasonably healthy, while others have health problems, such as heart or muscle disorders.

Most medical conditions that are caused by genetic diseases cannot be avoided. But it can be detected in the womb through chromosome examination, which allows parents to anticipate appropriate medical care to improve the quality of life of children after birth. Therefore, it is important that pregnant women regularly consult with obstetricians during pregnancy to detect early genetic abnormalities in the fetus.
