Genetic variations are the genetic basis of human life.
There are millions of variants that cause certain human diseases, as well as those that have been linked to other disorders, including diabetes, asthma, and cancer.
The human genome contains millions of genetic variants that affect genes, chromosomes, and protein structure.
As a result, scientists are able to identify many more variants than they could in the absence of such variation.
Here, we describe genetic variations and their genetic effects on the human genome.
The article starts with an overview of genetic variation and its effect on the genome.
Next, we review the various ways that the human body can respond to variations in the genome and discuss how genes are expressed and altered by variations in these genetic variants.
We then consider some of the most common and significant genetic variants and discuss the ways that these variations influence human health.
Finally, we discuss the implications of genetic variations for understanding human evolution and health and identify new ways to intervene to reduce genetic variation.
