Variations in two genes may increase the likelihood that a person will report suicidal thoughts after taking an antidepressant, researchers reported yesterday. The finding could help doctors develop tests to predict which patients will do well on such medications and which will react badly.
The authors of the study, which was released to reporters yesterday and will appear in The American Journal of Psychiatry on Monday, said that the findings were preliminary and would need to be verified by further testing.
The study focused on reactions to only one drug, Celexa from Forest Laboratories, and found no link between the gene variations and dangerous behavior like suicide attempts.

Success Or Failure Of Antidepressant Citalopram Predicted By Gene Variation
A variation in a gene called GRIK4 appears to make people with depression more likely to respond to the medication citalopram (Celexa) than are people without the variation, a study by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, has found.
The increased likelihood was small, but when people had both this variation and one in a different gene shown to have a similarly small effect in an earlier study, they were 23 percent more likely to respond to citalopram than were people with neither variation.
The finding addresses a key issue in mental health research: the differences in people's responses to antidepressant medications, thought to be based partly on differences in their genes. Some patients respond to the first antidepressant they attempt, but many don't. Each medication takes weeks to exert its full effects, and patients' depression may worsen while they search for a medication that helps. Genetic studies, such as the one described here, may lead to a better understanding of which treatments are likely to work for each patient.

Antidepressant studies find low birth-defect risk
Use of antidepressants by pregnant women doesn't significantly increase the risk of birth defects, with rare exceptions, two studies found.
The overall risk of having a child with a defect increased by less than 1 percent in women on the drugs, including Pfizer Inc.'s Zoloft, GlaxoSmithKline PLC's Paxil and Forest Laboratories Inc.'s Celexa, according to research published today in The New England Journal of Medicine.
