Objective: Microtia is defined as a congenitally defective external ear which has different degrees of severity from a simple isolated reduced size to complete loss of the ear. Normal fetal development is affected by the Glucocorticoids (GCs), which are critical for the maturation and development of different fetal tissues. The glucocorticoid receptors (GR) influence the GCs' actions. Therefore, we aimed to evaluate the association between the NR3C1 (encoding GR) gene BCL1 variant and its role in the development of non-syndromic microtia. Materials and Methods: Nineteen cases with microtia and forty healthy controls enrolled in the present study. We genotyped the NR3C1 BCL1 variant using the polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (RFLP) method. The patients and controls were compared in terms of allele and genotype distribution using the χ2 test. Results: No statistical association was found between the NR3C1 BCL1 genotype distribution and microtia risk. However, the NR3C1 BCL1 variant G allele was lower in patients than in the healthy controls (p=0.034, OR:2.411, 95%Cl: 1.115-5.212) . In the current study, our results suggested that the subjects carrying the G allele in the NR3C1 gene BCL1 variant had a lower risk of microtia. Conclusion: Further studies are needed to determine whether this gene variant has a role in the risk of developing the disorder.
