What can happen to a person's health and life when specific proteins are changed through mutations? best answer gets brainliest

Mutations are a source of genetic diversity in populations, and, as mentioned previously, they can have widely varying individual effects. In some cases, mutations prove beneficial to an organism by making it better able to adapt to environmental factors. In other situations, mutations are harmful to an organism — for instance, they might lead to increased susceptibility to illness or disease. In still other circumstances, mutations are neutral, proving neither beneficial nor detrimental outcomes to an organism. Thus, it is safe to say that the ultimate effects of mutations are as widely varied as the types of mutations
