Based on the results of this analysis, the ALOXE3 (arachidonate lipoxygenase 3), ALOX12B (arachidonate 12-lipoxygenase, 12R type), ALOX12E (arachidonate lipoxygenase, epidermal), ALOX15 (arachidonate 15-lipoxygenase), ALOX12 (arachidonate 12-lipoxygenase, 12S type), CMKLR1 (chemerin chemokine-like receptor 1), C1QBP (complement C1q binding protein) and ARRB2 (arrestin beta 2) genes could be associated with DD development. The gene discussed is ALOX15; the disease is dentin dysplasia.
