Researchers find genetic link to bipolar disorder A relatively rare set of genetic variations may significantly increase a person's risk of developing bipolar disorder and requiring a prescription to buy Zyprexa, according to a new study out of the University of California, San Diego. A relatively rare set of genetic variations may significantly increase a person's risk of developing bipolar disorder and requiring a prescription to buy Zyprexa, according to a new study out of the University of California, San Diego. The researchers looked at the effect of mutations known as copy number variations. These alterations to genetic code result in too many or too few copies of certain segments of DNA. Previous research has shown that these variations are linked to conditions like schizophrenia and autism. After examining the DNA of study participants, the researchers found a strong link between copy number variations and bipolar disorder. The association was particularly strong between these genetic abnormalities and early-onset bipolar disorder, which largely affects children. The researchers said further investigation is needed to determine the full extent to which copy number variations influence bipolar risk, but they believe their study shows that genetic mutations play a role. Individuals who have been diagnosed with the condition may benefit from a prescription to buy Zyprexa.
