“Yet there are complex, repetitive parts of our genome that are also known to cause diseases, such as Huntington’s disease, and these parts of the genome are not analyzed in most large medical genetics studies,” said Melissa Gymrek, PhD, assistant professor at UC San Diego School of Medicine and Jacobs School of Engineering.
So Gymrek and her team built a reference database that allows researchers to estimate a person’s genome at these repetitive regions, even when they are not directly measured.
“This resource will enable analyzing the effects of repeat variation for the first time across hundreds of thousands of individuals on thousands of traits without the need to collect any additional data,” Gymrek said.
