Genetic disorders are caused due to some abnormality in the DNA structure. The DNA structure contains proteins that follow the combination instruction provided by genes. Also, the combination of genes keeps on changing a bit from generation to generation. However, most of the gene structure remains the same, but while mating, it happens that to combine the DNA of two people, the structure changes. Thus, the change in structure would lead to some other gene combination, which would change the instructions for proteins. So, the extreme conditions where the difference does not support protein generation, genetic disorders occur. The identification of disease is through genetic tests.
Types Of Genetic Disorders
Three common types of genetic disorders occur in humans.
In this type, the DNA structure gets disturbed but only in traces. There are many genes in a DNA structure, and the only misplacement of one gene occurs. So, these types generate minor diseases such as sickle cell anemia.
Chromosomal Genetic Disorders
There are two types of chromosomes in a person’s body. The structure in the DNA requires a proper arrangement of chromosomes. However, misplacement of chromosomes in the construction or even if one of them is missing, then it causes disorders. The typical example of this disorder is Down syndrome.
The complex disorder occurs when there is a misplacement of two or more genes. However, this disorder can occur in regular life because of changes in lifestyles. So, the person needs to take special health care to get saved from the diseases. The typical example of complexity is any cancer.
The list below provides names of the diseases that can occur because of the problem in DNA structure.
The syndrome occurs when there is a defected combination of chromosomes. Doctors prefer to undertake tests such as prenatal and blood tests from the mother’s blood to understand the pattern of the chromosomes. However, the disease can occur even when the age of the mother is more at the time of birth. The common symptoms include delayed responses from the child, along with heart defects and muscle growth problems.
The disorder involves a problem with the generation of hemoglobin naturally. The situation prevails due to the faulty combination of gene structure from parents. Moreover, the child would develop the disease even if one parent has the disorder.
Sickle Cell Anemia
In general language, the disease involves blood clotting. The general shape of RBC is round, which changes to a sickle form when the child inherits the disease. Furthermore, the sickle shape tends to joint with other cells, which leads to clots. These clots can lead to organ damage or respiratory damage system. So, the person needs to take extra care if one of the parents has the disorder.
Thus, genetic disorders tend to damage the inner system of a person. However, sometimes, the cure for some diseases is possible if the person understands the symptoms in advance. So, the doctors always recommend undergoing body check-ups to capture a condition at an early stage.
