A ```genetic disorder``` , or genetic disease is a Disease caused by an unwelcome mutation. There are genetic disorders caused by the accidental duplication of a chromosome, as in Down syndrome, or repeated duplication of part of a chromosome as in Fragile X syndrome.
Other genetic disorders can frequently be explained as due to the change of a single DNA base in a gene, resulting in an enzyme or other protein either not being produced, or having altered functionality. This can be trivial and realtively harmless in its effects, such as color blindness, or lethal such as Tay-Sachs.
