Abstract

OBJECTIVES: The cell cycle regulator cyclin D1 plays an important role in parathyroid tumourigenesis. The NciI polymorphism in exon 4 has recently been associated with early onset of hereditary nonpolyposis colorectal cancer and is a prognostic indicator of nonsmall cell lung cancer and squamous cell carcinomas. Furthermore, a limited study of 28 primary hyperparathyroidism (pHPT) patients displayed a tendency of NciI influence on HPT development. We hypothesized that the NciI polymorphism may relate to a risk of developing pHPT.

DESIGN, SETTING AND SUBJECTS: We genotyped 182 patients with sporadic pHPT and matched controls for the cyclin D1 polymorphism. A total of 88 pHPT patients and controls were recruited via a... (More)

OBJECTIVES: The cell cycle regulator cyclin D1 plays an important role in parathyroid tumourigenesis. The NciI polymorphism in exon 4 has recently been associated with early onset of hereditary nonpolyposis colorectal cancer and is a prognostic indicator of nonsmall cell lung cancer and squamous cell carcinomas. Furthermore, a limited study of 28 primary hyperparathyroidism (pHPT) patients displayed a tendency of NciI influence on HPT development. We hypothesized that the NciI polymorphism may relate to a risk of developing pHPT.

DESIGN, SETTING AND SUBJECTS: We genotyped 182 patients with sporadic pHPT and matched controls for the cyclin D1 polymorphism. A total of 88 pHPT patients and controls were recruited via a health-screening.

RESULTS: The frequency distribution of the NciI genotypes NN, Ni, and ii were in pHPT patients and controls 22, 44 and 34%, and 26, 49 and 25%, respectively. The calculated allele frequencies were A = 0.56; G = 0.44 in cases and A = 0.49; G = 0.51 in controls. The frequency distributions did not differ comparing cases and controls when subgrouped after age and menopausal status. The NciI genotypes were not significantly associated with age of the individuals, serum (s)-calcium, s-parathyroid hormone (PTH), bone mineral density (BMD) or parathyroid tumour weight in any of the groups of pHPT patients or controls.

CONCLUSIONS: No significant differences in distribution of the genotypes could be detected between the groups, suggesting that the polymorphism has minor or no pathogenic importance in the development of pHPT. Our results suggest that determination of the NciI polymorphism in the cyclin D1 gene is not a clinically useful tool for prediction of pHPT.
