Genetic heterogeneity and polygenic traits can both make it more difficult to identify disease genes. Genetic heterogeneity refers to the fact that a particular disease can be caused by mutations in different genes, while polygenic traits refer to the fact that many traits and diseases are influenced by multiple genes, each with a small effect. Both of these factors can make it more challenging to identify the specific gene or genes responsible for a particular disease. The location of the gene on the X chromosome is also a potentially complicating factor in some cases, but genetic heterogeneity and polygenic traits are more generally relevant to many different types of diseases.
