Detail Info
Sample Diagnosis |
DSM-IV |
Related Diagnostic Tools |
the Preschool Age Psychiatric Assessment (PAPA). The PAPA interview was performed by trained research assistants who were blind to genotyping information. |
Sample Status |
Children could not participate if they had moderate mental retardation, autistic disorder, deafness, blindness, or were non-English speaking. |
Controls Exposed |
NA |
Replication Size |
None |
Result Summary |
A diagnosis according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, total symptoms, and specifically Criterion D symptoms were significantly more likely to be found in children with the 9 allele. |
Potential Biomarker |
None |
