Answer

Most genetic mutations have no negative impact on health or development. Some mutations will change a gene's DNA sequence but have no effect on the function of the protein that is synthesized from the gene. Gene mutations that could cause disorder are oftentimes repaired by designated enzymes before the gene is expressed in the form of a defective protein.
