April 29 (Reuters) - U.S. stock index futures were lower on Wednesday as investors await the outcome of the two-day Federal Reserve meeting and ahead of U.S. economic growth numbers for the first quarter.
* The Fed is not expected to raise interest rates. But investors will closely examine the central bank's statement for clues on when rates are likely to be increased, as a batch of soft data could push back the timing of a hike until the end of the year. The statement is expected at 1400 p.m. EDT (1800 GMT).
* U.S. gross domestic product likely braked sharply in the first quarter as harsh weather dampened consumer spending and energy companies struggling with low prices cut spending. GDP probably expanded at a 1.0 percent annual rate, down from the 2.2 percent growth rate in the fourth quarter.
GDP numbers are due at 8:30 a.m. EDT (1230 GMT).
* Twitter shares were up 0.5 percent at $42.48 in premarket trading. The stock slumped as much as 24 percent after market on Tuesday as the company cut its full-year forecast due to weak demand for its new direct response advertising.
* Lumber Liquidators slumped 15.4 percent to $28.25 after reporting a 2 percent fall in net sales so far in April and did not provide a full-year forecast.
* Time Warner Inc shares rose 1.2 percent to $69.00 after the company's revenue rose 5 percent.
* Companies expected to report results on Wednesday include MasterCard, Marriott International and Yelp .
