}}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.{{PMID|18205172}}
