Potential novel biomarker for alcohol dependence

Specific molecules (small noncoding microRNAs or miRNAs) found in saliva may be able to predict alcohol dependence as biomarkers. This is the first study to examine changes in the miRNA expression in the saliva of people with alcohol dependence. Currently, no genetic markers exist to test for this condition.
