      A single-gene disorder is caused by a change in one specific gene, such as cystic fibrosis or sickle cell disease. A chromosomal disorder involves a larger change, such as an extra, missing, or rearranged chromosome, such as Down syndrome. Both are detected through different types of genetic tests.
