As the article from lifeSite News states:
This is such good news for patients everywhere. Gene patenting has affected you directly whether you know it or not. Because a company legally “owns” a gene sequence, they control who is able to test or research that gene. In the case of genetic testing, labs are limited on what genes they can offer tests for because of gene patents, which limits the choices they can offer patients. Labs that are allowed to test a patented gene pay royalties to the companies that own the genes which drives up the cost of the genetic test. Many labs, like ones I have worked in, just chose not to offer the test at all.
