The relationship between polymorphisms of BDNFOS and BDNF genes and heroin addiction in the Han Chinese population
ReviewTianbo Jin et al.(2016)· The Journal of Gene Medicine

This review examines neurogenetic and neuropharmacological correlates of opioid use disorder (OUD) with emphasis on ancestry-specific genetic risk profiles. The paper identifies multiple genes involved in the reward pathway (DRD2, DRD3, DRD4, OPRM1, OPRK1, OPRD1, BDNF, NRXN3, COMT, SLC6A4, KCNC1, KCNG2) and their variants associated with OUD susceptibility and treatment response across different ethnic populations, highlighting critical research disparities where African Americans and Hispanics have been underrepresented in genetic association studies.

About DRD4

This gene encodes the D4 subtype of the dopamine receptor. The D4 subtype is a G-protein coupled receptor which inhibits adenylyl cyclase. It is a target for drugs which treat schizophrenia and Parkinson disease. Mutations in this gene have been associated with various behavioral phenotypes, including autonomic nervous system dysfunction, attention deficit/hyperactivity disorder, and the personality trait of novelty seeking. This gene contains a polymorphic number (2-10 copies) of tandem 48 nt repeats; the sequence shown contains four repeats. [provided by RefSeq, Jul 2008]
