Researchers have identified more than 4,000 diseases that are caused by mutations. But having a genetic mutation that may cause a disease or condition doesn’t always mean that a person will actually develop that disease or condition.
What diseases are caused by genetic mutations?
Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others. All of these disorders are caused by the mutation of a single gene.
How common are genetic mutations?
One in five ‘healthy’ adults may carry disease-related genetic mutations.

What is the most common genetic mutation?
In fact, the G-T mutation is the single most common mutation in human DNA. It occurs about once in every 10,000 to 100,000 base pairs — which doesn’t sound like a lot, until you consider that the human genome contains 3 billion base pairs.
What are some examples of genetic mutations?
Other common mutation examples in humans are Angelman syndrome, Canavan disease, color blindness, cri-du-chat syndrome, cystic fibrosis, Down syndrome, Duchenne muscular dystrophy, haemochromatosis, haemophilia, Klinefelter syndrome, phenylketonuria, Prader–Willi syndrome, Tay–Sachs disease, and Turner syndrome.
How often do genetic mutations occur?
Extrapolating that result to the whole genome gives a mutation rate of around one in 30 million base pairs.
How many genetic mutations does the average human have?
The average mutation rate was estimated to be approximately 2.5 x 10(-8) mutations per nucleotide site or 175 mutations per diploid genome per generation.
What percent of the population has a genetic disorder?
Finally, medical investigators estimate that genetic defects—however minor—are present in at least 10 percent of all adults.
