Background: The cyclin D1 gene (CCND1) is a proto-oncogene playing a critical role in the transition through the G1 ot the S phase of the cell cyle and is overexpressed in many tumors. G870A plymorphism at the exon4/intron4 splicing region of the CCND1 gene may play a role in pituitary tumorigenesis and invasiveness. The objective of this study was to examine CCND1 polymorphism i patients with different types sporadic pituitary adenomas.
