PSPG hits the streets to explain how genes make us who we are
Kids learned how genes act as the instructions for building
an organism by drawing alleles for different traits out of a hat and using the
genotype to decide how to put together a “monster.” In so doing, they were
exposed to the basic principles of genetics (dominant vs. recessive alleles,
complete vs. incomplete dominance, and codominance), and they got to leave with
a cute pipe-cleaner monster too.
Our exhibit also featured a section entitled “How Myriad
Genetics Almost Owned Your Genes” which highlighted the recent Supreme Court case
brought against a biotech company that wished to patent two genes (BRCA1 and
BRCA2) involved in the development of breast cancer. The genes were discovered
at the University of Utah in a lab run by Mark Skolnick, who subsequently
founded Myriad Genetics. Myriad went on to develop a high-throughput sequencing
assay to test patients for breast cancer susceptibility and eventually obtained
patents for both genes. This was controversial for several reasons: 1. These genes
exist in nature in every human being and are not an invention; 2. The genes
were originally discovered with public funding; and 3. Myriad had a monopoly on
testing for BRCA mutations and prevented universities and hospitals from
offering the tests. Last year in Association
for Molecular Pathology v. Myriad Genetics, several medical associations,
doctors and patients sued Myriad to challenge the patents and the Supreme Court
decided that patenting naturally occurring genes is unconstitutional (however
synthetically-made complementary DNA is still eligible for patenting). It is
likely that the patenting of DNA sequences will continue to be an issue in the
future considering recent advances in the field of synthetic biology.
