Genetic Disorders

Hereditary diseases are diseases caused by specific mutations in DNA. There are various genetic diseases caused by different genes, each with very different symptoms. There are three types of hereditary diseases: monogenic diseases, chromosomal abnormalities, and multifactorial diseases. In this article I will explain possible treatments for three types of hereditary diseases, examples of each kind and specific diseases such as Huntington's disease, Down's syndrome, Alzheimer's disease.

Human genetic diseases are caused by abnormalities in individual genetic material. Depending on the cause, the type of human genetic disease is different. There are four genetic diseases: single gene, chromosome, multifactorial, mitochondrial. Hereditary diseases are caused mainly by gene and DNA mutations. There are different reasons for each type of illness. For example, chromosomal abnormalities are caused by chromosomal mutations. Exchanging DNA through chromosomes to form multiple gene pools can cause disorders leading to regional changes. Human genetic diseases occur through abnormalities in genes and chromosomes. Certain diseases such as cancer are the result of hereditary diseases, but they can occur due to environmental factors. Most human hereditary diseases are rare and one in 1 million people has developed. Several recessive genetic diseases prefer heterozygote states in certain circumstances

Genetic diseases are diseases caused by all or part of DNA sequence changes away from normal sequences. Hereditary diseases can be caused by genetic mutations (single genetic diseases), polygenic mutations (multifactorial genetic diseases), combinations of genetic and environmental factors, or chromosome damage (amount or structural change) . It is responsible for the entire chromosome and the structure of the gene. When we elucidate the secret of the human genome (the complete collection of human genes), we discover that almost all diseases have genetic elements. Several diseases are caused by mutations inherited from parents, such as sickle cell disease, and are present in individuals at birth. Other diseases are caused by acquired mutations in genes or genomes occurring in their lives. Such mutations do not inherit from parents, but occur randomly or due to certain environmental exposures (eg, cigarette smoke)

Many human diseases have genetic factors. There are over 6,000 hereditary diseases, many of which are fatal or severe debilitating. Hereditary diseases are caused by DNA mutations and can be divided into four categories: single gene mutation, multiple gene mutation, chromosomal alteration and mitochondrial mutation. Completion of the Human Genome Project in 2003 will help to identify genes associated with many genetic diseases. As a result, scientists can conduct genetic testing to predict future diseases, including diagnosis of diseases, confirmation of disease condition, even reaction to treatment. More than 2,000 genetic tests are currently available. In this infograph, we gathered information on the 10 most common genetic diseases.
