It is estimated that 4.6 of SNPs and about 17 of all genes can be defined as pleiotropic. Based on this finding, which of the following should a consumer of genetic information keep in mind?
 
  A) A test identifying a gene for a disease might actually be a test for a different disorder instead.
  B) Any variant that we gain information about might in the future be found to associate with a more stigmatizing condition.
  C) A physician might be treating the major condition but not notice even more deleterious outcomes.
  D) The classification of my genetic disorder might be incorrect.
  E) Sequencing of the candidate gene might find the wrong expected functional significance.
