SAN DIEGO — After starting off the year with lower revenue projections than market analysts had hoped for, San Diego-based genomics giant Illumina lowered expectations again on Wednesday, forecasting annual growth of 1% compared to the previous year.

The market’s response was swift. Minutes after the company issued its press release, shares in Illumina dipped from $184.49 to below $172 during after-hours trading.
