Objective. The genetic structural alterations in the majority of somatotroph adenomas are not clarified and the search for novel candidate genes is still a challenge. We aimed to investigate possible associations between vitamin D receptor VDR polymorphisms and acromegaly. Design, Patients, and Methods. 52 acromegaly patients mean age years and 83 controls mean age years were recruited to the study. VDR polymorphism was determined by polymerase chain reaction-based restriction fragment length polymorphism methods. Results. The distribution of VDR genotypes showed a significant difference in the frequencies of VDR FokI genotypes between patients and controls . VDR FokI ff genotype was significantly decreased in acromegaly patients and carriers of FokI Ff genotype had a 1.5-fold increased risk for acromegaly OR: 1.5, 95% CI: 1.07–2.1; . IGF1 levels after treatment were significantly higher in patients carrying the Ff genotype compared to carrying ff genotype . 25OHD3 levels were significantly lower in acromegaly patients . Conclusions. Our study suggests that VDR FokI genotypes might affect the development of acromegaly and VDR polymorphisms may play a role in the course of acromegaly as a consequence of altering hormonal status.
