Professor, researcher helped discover disease-causing genes

- By Richard Sandomir Richard Sandomir is a New York Times writer.

Deborah Nickerson, a human genomics researcher who helped discover genes responsibl­e for cardiovasc­ular disease, autism and Miller syndrome, a rare condition that causes malformati­ons of the face and limbs, died Dec. 24 at her home in Seattle. She was 67.

Her brother, William Nickerson, who is her only immediate survivor, said the cause was abdominal cancer, which had been diagnosed less than a week earlier.

In her research, Deborah Nickerson employed the findings of the Human Genome Project, which completed its historic genetic sequencing of every human gene in 2003, and made them medically useful. By sequencing the genes of thousands of healthy people, she revealed how genetic variation could be used to target specific genes that cause inherited disorders.

“Her imprint on genomic medicine is profound,” said Dr. Gail Jarvik, a professor of medicine and genome science at the University of Washington School of Medicine. “Her role was in really helping us understand what changes in DNA among people meant, and in identifyin­g what gene was changed in rare diseases.”

Nickerson was also a professor of genome sciences at the University of Washington and was a founder and director of one of the five clinical sites that make up the Gregor Consortium, the successor to the Centers for Mendelian Genomics, named after Gregor Mendel, a 19th century Austrian monk known as the father of genetics.

Funded by the National Institutes of Health, the consortium seeks to identify gene mutations responsibl­e for what are known as Mendelian disorders, in which patients have a mutation in one gene, like that for cystic fibrosis or sickle cell anemia.

Working with Drs. Michael Bamshad and Jay Shendure, Nickerson found the gene for Miller syndrome, one of about 7,000 Mendelian disorders, in 2009.

Dr. Francis Collins, a former director of the NIH who is now a senior investigat­or at the National Human Genome Research Institute, a part of the NIH, called the discovery of the Miller syndrome gene “an explosive moment” and a “jawdroppin­g” example of genome sequencing, the technique used to read all or part of a person’s genome, an organism’s complete set of DNA.

“I never envisioned that we’d be able to do that in my career or lifetime,” he said, referring to the ability to determine a person’s illness by reading his genome.

“Debbie was instrument­al in developing the technology so that we could prove it could be done on other conditions,” Bamshad said. “She was a great, hard-nosed scientist passionate about the role of trainees and women in science.”

The technology that Miller and her colleagues used led a year later to the discovery of genetic alteration­s that are responsibl­e for Kabuki syndrome, a rare congenital disorder that causes children to be born with elongated eyes and arched eyebrows (The term derives from the appearance of actors using exaggerate­d makeup in Kabuki theater.) Deborah Ann Nickerson was born in Mineola, N.Y. Her parents, William and Josephine (Veccia) Nickerson, owned a garden center.

She graduated from Adelphi University in Garden City, N.Y., in 1974 with a bachelor’s degree in biology and received her doctorate in immunology from the University of Tennessee. She was a postdoctor­al scholar in the division of infectious diseases from 1978 to 1979 at the University of Kentucky’s college of medicine.

“I love science,” she said in a video on her university

homepage. “It was probably my hardest subject in school, and that’s why it drives me. You want to get better and understand more.”

Starting in 1979, Nickerson spent nearly a decade teaching biology at the University of South Florida before joining the biology department at the California Institute of Technology, first as a visiting associate and then as a senior research scientist. There she worked under Dr. Leroy Hood, who led the team that invented the DNA sequencer, which made the Human Genome Project possible.

She followed Hood to the University of Washington’s newly created department of molecular biotechnol­ogy in 1992. After it merged with the university’s department of genetics in 2001, she stayed to form the department of genome sciences.

Nickerson was an early adapter of technologi­es that made DNA sequencing less expensive; using them, she created a catalog of human genetic variation from a diverse population by sequencing the genes of more than 6,500 volunteers. She then made it available online to other researcher­s, who have advanced it further.

She also led a group of researcher­s who in 2017 reported finding genetic variants among patients’ different responses to the blood thinner warfarin, which had been a long-standing clinical problem.

Nickerson’s creative, unfiltered, tenacious style served her well in advising women and under-served minorities in her field, having risen in what had been a male-dominated world; in fighting for what she wanted when applying for grants; and in dealing with the leadership of the NIH and its National Human Genome Research Institute.

“I was the NHGRI director for less than an hour, and she was telling me how to do my job,” said Eric Green, who was appointed to that position in 2009. “The remarkable part is that she was almost always completely right.”

Jarvik recalled how Nickerson would counsel her on seeking grant money, encouragin­g her to ask for more and to aim higher. “She had entreprene­urial instincts,” she said, “and she understood big opportunit­ies.”

She added, “I’m not a native risk-taker, and I’ve tried to ask myself, ‘What would Debbie do?’ ”
