Implicated as part of a haplotype of the dopamine D1 receptor DRD1 gene associated with autism spectrum disorders in families having only affected males. The haplotype is rs265981(C)-rs4532(A)-rs686(T) as published, though not necessarily as oriented in dbSNP. Significant association of DRD1 with nicotine dependence. A haplotype of the DRD1 gene is associated with alcohol dependence.
