Biologically Significant Variants
DRD4 7-repeat allele may increase likelihood of ADHD.
Type:  Repeat polymorphism of Exon III
Species:  Human
References:  7,44
General Comments
Human and primate receptors have a variable number (2-10) of imperfect 48 bp repeats in exon 3 [19,49]. This leads to a highly variable length and aa composition of the putative third cytoplasmic loop, apparently not associated with any marked variation in pharmacology. Most D4 receptor-antagonists display agonistic activities in some heterologous expression systems [10-11].
