Multifactorial Disorders....
A large number of disorders fall into this category - including asthma, insulin-dependent diabetes mellitus, schizophrenia, and a number of conditions present at birth such as clubfoot and cleft lip and palate.
In each case, suspectibilty to the disorder is thought to be determined by a number of different genes that, ALONG WITH ENVIRONMENTAK INFLUENCES, have an additive effect. The degree to which suspectibility is determined by genes has been estimated and is termed heritablity.
