Multifactorial Diseases

Multifactorial illnesses are not restricted to any one pattern of single gene inheritance and are more likely to be linked to the interactions of numerous genes with environmental influences. In reality, the terms "multifactorial" and "polygenic" are interchangeable and frequently used to characterise the genetic architecture of diseases. Multifactorial illnesses are frequently seen clustered in families, although they do not exhibit any clear patterns of inheritance.
