Genetics: More than merely a mutated gene

In the current issue of PLoS Genetics, Michigan State University genetic scientists have begun to understand how the rest of the genome interacts with such mutations to cause the differences we see among individuals. "It’s been known for a while that genetic mutations can modify each other’s effects," said Ian Dworkin, MSU associate professor of zoology and co-author of the paper. "And we also know that the subtle differences in an individual’s genome — what scientists call wild type genetic background — also affects how mutations are manifested." Dworkin and Sudarshan Chari, zoology doctoral student and the paper’s lead author, wanted to know how common it was for wild type genetic background to alter the way genetic mutations interact with each other. …
