Task: Answer Verification
Input (English): Question: Is sTin2 VNTR polymorphism associated with comorbid tobacco use and mood disorders?
Answer: The STin2.12 allele is positively and the STin2.10/10 genotype is negatively associated with comorbid TUD and mood disorders, depression or bipolar depression, suggesting that biological endophenotypes, e.g. disorders in serotonin metabolism, may in part underpin this comorbidity.
