Researchers at Stanford University have identified a case of a new coronavirus variant with two mutations, which was first detected in India last month. The variant was found in a patient in the San Francisco Bay Area, university officials announced on Saturday.

“We believe this is the first described case with this variant in the United States,” Lisa Kim, a spokeswoman for Stanford Health Care, told NBC News in a statement.

The variant has two mutations in the spike protein of the coronavirus that allows it to attach to cells. Indian health officials first detected the variant last month. The “double mutation” could be of concern if the variant is more transmissible or deadly, but health officials have not yet called it a “variant of concern.”

“There is no definite evidence that this double variant is more virulent or causes more severe disease,” Dean Winslow, MD, an infectious disease specialist at Stanford University, told NBC Bay Area.
