Background: Multiple myeloma (MM) primarily origins from terminally differentiated B cells. The Cyclin D1 (CCND1) gene polymorphism is located on the long arm of chromosome 11 in exon 4, and coding of the Cyclin D1 protein is reported in MM. This study aimed at investigating the relationship between CCND1 polymorphism and MM in northern part of Iran. Materials and Methods: This case–control study was performed on 87 patients with MM (case group) and 70 healthy individuals (control group). The population was selected from Touba Clinic, the largest referral center in Mazandaran province, Iran. Data analysis was done in SPSS software version 19. Results: The participants were aged 18–83 years (mean age: 53.8 ± 16.7 years), including 72 (45.9%) males and 85 (54.1%) females. The adjusted odds ratio (aOR) for GG genotype was found to be significant (aOR = 4.28, confidence interval [CI] 95% = 1.21–15.13). In addition, the presence of G allele compared to allele A increased the odds ratio (OR) of MM (OR = 2.28, CI 95% = 1.45–3.57). The age and sex aOR by age and sex was 2.08, CI 95% = 1.10–3.93. Conclusion: The current study elucidated that, unlike most previous surveys on Cyclin D1 G870A gene polymorphism that associated AA genotype with various types of malignancies, the GG genotype is a risk factor for MM.
