[|Klinefelter's syndrome] Genetics Research

A **genetic disorder** is an [|illness] caused by abnormalities in [|genes] or [|chromosomes], especially a condition that is present from before birth. Most genetic disorders are quite rare and affect one person in every several thousands or millions. A genetic disorder may or may not be a **heritable disorder**. Some genetic disorders are passed down from the parents' genes, but others are always or almost always caused by new mutations or changes to the DNA. In other cases, the same [|disease], such as some forms of cancer, may be caused by an inherited genetic condition in some people, by new mutations in other people, and by non-genetic causes in still other people. Some types of [|recessive gene] disorders confer an advantage in the [|heterozygous state] in certain environments.
