DCG—Disorders with Complex Genetics Introduction: Complex genetic disorders and disorders with complex genetics

In medicine and medical genetics, one often encounters the phrase complex genetic disorder to refer to many common syndromes like diabetes, cancers, and hypertension. The definition of a complex genetic disorder is quite simple—it is a disorder that has something genetic going on behind it but no one has a clue as to what the genetics are. The term complex genetic disorder is actually a misnomer because it implies that the disorder is genetic whereas empirical research usually shows that the environment can play a large etiological role. To insure that we do not neglect the environment, the term disorder(s) with complex genetics (DCG) will be used.
