Genetic Diseases 

Genes are the fundamental components of heredity. They are normally passed down from generation to generation. They contain DNA, which includes the instructions for proteins manufacture. These proteins perform the majority of the work within cells. For instance, they transport molecules, make structures, break down toxins, and perform a variety of other maintenance tasks. 

A mutation refers to a change in the gene or genes that can occasionally occur. This mutation alters the instructions of the gene for producing a protein, causing the protein to malfunction or go missing completely. This could lead to medical conditions known as genetic diseases. 

A child can inherit the gene mutation from either one or both parents. Such a mutation can occur during a person’s lifetime as well.
