NR3C1 and dentin dysplasia: Additionally, patients displayed decreased glucocorticoid receptor NR3C1 expression compared to controls at posttreatment (5.20E − 01 versus 7.90E − 01; F = 8.70, P = 0.006, and Cohen's f = 0.476), although expression of this gene was not significantly increased in DD patients at pretreatment.
