Various Genetic Disorders

Human genetic alteration or deletion of key gene products of various genetic diseases is usually caused by mutations that can cause numerous genetic mutations and mis-coding. Mutations may result from deletions, duplications or inversions of chromosomes. This erroneous deletion is a factor that causes complications and ultimately causes hereditary disorders. Turner syndrome and cat cry syndrome are changes in chromosome structure due to deletion.

The term "intellectual disorder" refers to a group of diseases caused by various genetic diseases and infectious diseases. Mental retardation is usually determined in childhood and has sustained impact on individual development. Mental retardation can be defined as understanding new or complex information, acquiring new skills, and a drastic drop in the ability to uniquely respond to social functions. There are many types of mental retardation with varying degrees of severity, as well as groups of people with all disabilities. These include major differences in the nature and extent of mental retardation and functional limitations, the causes of disability, the personal background and personal social circumstances. The genetic diseases of some people have a profound effect on their intelligence, social and other functions.

Different hereditary diseases are usually caused by defective genes. Through gene therapy, treatment does not treat the symptoms of the disease, but it can also fix the fundamental cause of the disease and eventually correct the wrong gene to a normal gene. One of the genetic diseases using gene therapy as an alternative treatment is cystic fibrosis. Cystic fibrosis (CF) is one of the most famous hereditary lethal diseases. A study by the British Cystic Fibrosis Gene Therapy Association (CFGTC, UK) showed that about 50,000 newborns and 2,500 newborns are affected worldwide. CF is an autosomal recessive disorder caused by mutation of the cystic fibrosis transmembrane conductance regulator (CFTR) protein, resulting in abnormal mucous secretion. The organs most affected by CF are lung, intestine, pancreas, liver, reproductive tract, but pulmonary infection is most affected by CF. (Quoted from Metharom, 1997)

Human genetic disorders are diseases caused by chromosomes or genetic abnormalities. Several diseases, such as cancer, are part of hereditary diseases, but they can also be caused by environmental factors. Many diseases are very rare and one in one million people suffer. There are several types of recessive inherited diseases that have the advantage of being heterozygous in some circumstances. Both genetic and environmental factors are involved in the onset of any disease. Human genetic diseases are caused by abnormalities in individual genetic material. There are four genetic diseases: single gene, chromosome, multifactorial, mitochondrial. Single gene disorder is caused by a single mutated gene. This disease can spread to the next generation in various ways. The disease is caused mainly by mutation or change in the DNA sequence of the gene. Chromosomes are caused by abnormalities caused by chromosomes
