Molecular Diseases: Understanding Inherited Diseases Caused by Structural Abnormalities of Proteins

In the world of medicine and science, the boundaries of our understanding of diseases and their occurrence are constantly advancing. One of the most interesting and challenging aspects is diseases of molecular origin. Such diseases arise due to structural disorders of proteins, most often enzymes, due to mutations of genes responsible for the primary structure of these proteins.

Inherited diseases associated with molecular defects are the result of genetic changes passed from generation to generation. These changes, or mutations, can occur in genes that encode information about the structure of proteins. They can lead to incorrect formation of protein molecules or disruption of their functions. When such molecular abnormalities occur in enzymes, they can significantly affect the chemical reactions in the body, ultimately leading to various diseases.

An example of hereditary diseases caused by molecular defects is phenylketonuria. This is a rare genetic disease characterized by a disorder in the metabolism of the amino acid phenylalanine. The body normally processes phenylalanine using the enzyme phenylalanine hydroxylase, but in people with phenylketonuria this enzyme is either missing or does not function properly due to a mutation in the gene that codes for its structure. As a result, phenylalanine accumulates in the body and can cause serious problems such as mental retardation and nervous system dysfunction. Often, patients with phenylketonuria are prescribed a special diet that limits their intake of phenylalanine.

Another example of a disease caused by molecular defects is cystic fibrosis. It is an inherited disease caused by a mutation in the gene responsible for producing a protein called cystic fibrosis transmembrane conductance regulator (CFTR). This protein plays an important role in regulating ion transport across cell membranes. A mutation in the CFTR gene causes the protein to malfunction, causing thick secretion to form in various organs such as the lungs, liver and pancreas. This leads to chronic problems with the respiratory system, digestive system and other complications.

Such molecular defects can have different effects on the body, depending on which protein or enzyme is affected by the mutation. Some hereditary diseases can be mild and have minimal impact on health, while others can be severe and lead to serious complications and limitations in the patient's daily life.

In light of the rapid development of molecular genetics and biology, research into diseases of molecular origin is becoming increasingly relevant. Scientists and doctors are constantly looking for ways to prevent and treat such diseases. One approach is genetic therapy, which aims to correct defective genes or introduce normal genes to replace mutant ones. This is an area of ​​active research and promising technologies that may in the future lead to new ways to treat and prevent diseases of molecular origin.

In conclusion, diseases of molecular origin caused by structural abnormalities of proteins are a challenging area to study and understand. Hereditary diseases associated with molecular defects occur as a result of mutations in genes encoding the primary structure of proteins. These defects can have serious consequences for the functioning of the body and the health of the patient. However, thanks to the constant development of scientific research, we are gaining more and more knowledge about the molecular aspects of diseases and are developing new approaches to their treatment and prevention. This opens the door to future advances in medicine and improved health for people suffering from diseases of molecular origin.

Disease is a painful state of the body, a deviation from the norm of its function. The components of a single biological process are: disease - a healthy cell similar to a sick one. There is a genetic stock of these cells (mutant) due to mutation. In the second case, patients have disorders of certain types of metabolism, a mutation
