Variable penetrance

Variable penetrance

The expression of a genetically inherited trait in different forms or degrees in different people. For example, the alleles for the Down syndrome genes may cause an effect in the phenotype of some individuals but not others. As a result, there is considerable variability within the Down syndrome population in regards to susceptibility to the characteristic unpleasant medical problems.
