This is BREAKING NEWS. So not much info yet.
I will update if any new info comes out. But her reason seems depressing
Romer To Leave White House
"She has been frustrated," a source with insight into the WH economics team said. "She doesn't feel that she has a direct line to the president. She would be giving different advice than Larry Summers [director of the National Economic Council], who does have a direct line to the president."
"She is ostensibly the chief economic adviser, but she doesn't seem to be playing that role," the source said. The WH has been pounded for its faulty forecast that unemployment would not top 8% after its economic stimulus proposal passed.

BREAKING: Christina Romer To Resign From WH
She'll be more likely to keep the conversation going and add any additional news than I will be able to tonight.
UPDATE II: As RandomActsOfReason suggested in the comments below I want to emphasize that this is currently a rumor. Nothing has been confirmed. We probably won't get any facts until sometime in the next few days. I also updated the title to reflect this.
UPDATE III: The Wall Street Journal is reporting that Romer is resigning.
Romer to Resign as Obama Adviser
WASHINGTON—Christina Romer said she would resign as chairman of President Barack Obama's Council of Economic Advisers to return to her teaching post at the University of California at Berkeley, effective Sept. 3.

Ms. Romer has been mentioned as a possible successor to Janet Yellen as president of the Federal Reserve Bank of San Francisco. Ms. Yellen has been nominated to be vice chairman of the Federal Reserve Board in Washington.
Ms. Romer will join the President's Economic Recovery Advisory Board, which is chaired by former Fed Chairman Paul Volcker. Among the candidates to succeed her at the Council of Economic Advisers is Austan Goolsbee, who is on leave from the University of Chicago's Booth School of Business.
UPDATE IV: The NY Times publishes a short statement from President Obama:
“Christy Romer has provided extraordinary service to me and our country during a time of economic crisis and recovery,” the President said. “The challenges we faced demanded more of Christy than any of her predecessors, and I greatly valued and appreciated her skill, commitment and wise counsel.”

UPDATE VI:
The NY Times Top Obama Adviser on Economics to Step Down
WASHINGTON — Christina D. Romer is resigning as the chairwoman of President Obama’s Council of Economic Advisers, the White House announced on Thursday night. She will be the second member this summer to leave an economic team that has steered the administration through the worst recession since the Depression.
Ms. Romer, the only woman in the inner circle of Mr. Obama’s economic advisers, early on had tense relations with Lawrence H. Summers, who, as director of his National Economic Council, coordinates the advice that goes to the president.
But according to the announcement, Ms. Romer wanted to return to her tenured position as an economics professor at the University of California, Berkeley, in time for her son to begin high school in California this fall. Her resignation is effective Sept. 3.
