In her humble first-floor apartment, Katherine Aull is searching for a killer that has stalked her family for generations.
But this is no manhunt. Aull is scouring her own genes in pursuit of a potentially lethal mutation that she may have inherited from her parents — and she has transformed her bedroom closet into a makeshift scientific laboratory to conduct the hunt.
The 23-year-old MIT graduate uses tools that fit neatly next to her shoe rack. There is a vintage thermal cycler she uses to alternately heat and cool snippets of DNA, a high-voltage power supply scored on eBay, and chemicals stored in the freezer in a box that had once held vegan “bacon” strips.
Aull is on a quirky journey of self-discovery for the genetics age, seeking the footprint of a disease that can be fatal but is easily treated if identified. But her quest also raises a broader question: If hobbyists working on computers in their garages can create companies such as Apple, could genetics follow suit?
“We have a long way to go,” Aull said. “But certainly in the short term, I’d like to show people how to do this, how to do it safely, and that you can do this.”
Aull, a former research associate at the now-defunct biotech company Codon Devices, doesn’t expect everyone to approach genetics with her same attitude. But with startup companies already gambling that knowing your genes could become as routine as a blood-pressure test, she figures, why not test the theory?
She has the attention of George Church, a Harvard Medical School genetics professor who was a pioneer of the Human Genome Project and a co-founder of Codon Devices, and who is now leading an effort to sequence the DNA of 100,000 people. Aull is one of his former students.
“Can genetics map onto electronics — is it ready to go into the garage shop in a hobbyist sense?” said Church. “That’s the question she’s asking, and I think that’s a very big, profound question ... There seems to be a very deep and growing curiosity about genetics that might dwarf electronics. No matter how much we love our gadgets, we’re totally fascinated by our ancestry and health.”
Aull’s quest began with her father, Ken Aull, who began to get sick a few years ago, when he was 58. His blood pressure spiked, and he had back pain and signs of liver problems.
The elder Aull, an engineer, went through a battery of tests, including a genetic test that revealed he had hemochromatosis, in which iron builds up in the body. He turned to his daughter, a biologist in training, for more insight.
Katherine Aull sifted through the data and saw that her father had mutations on each copy of one of his genes. Together, they gave him hemochromatosis, a potentially fatal disease with a simple treatment: have blood drawn regularly.
Today, with treatment, her father is fine, but she has been left wondering about herself. Each person inherits two copies of each gene: one from their mother and one from their father. Aull knows she must have inherited one mutant gene from her father. But it takes two mutant genes to cause hemochromatosis. The question is whether she inherited another from her mother.
Instead of going to a doctor to do the test, she recently prepared her samples by swabbing her cheek with a Q-tip and scraping the cells into a tube. Then, she dangled the tube in a pot of boiling water on her kitchen stove.
