Researchers from Johns Hopkins University have identified six areas of the human genome believed to lead to susceptibility for Obsessive Compulsive Disorder (OCD).
In an analysis of DNA from 1,008 individuals from 219 families with two or more obsessive-compulsive siblings, six regions on five different chromosomes were identified as areas where the gene or genes associated with the disorder are probable to be found. Researchers hope to further analyze these regions to identify the specific genes indicating OCD susceptibility.
They emphasize, however, that any genes found do not mean a person will have OCD but merely increase the chance of developing it in conjunction with other factors such as environment.
