Background: Calmodulin 1 (CALM1) mutations are involved in the development of coronary artery disease (CAD). However, the relationship of CALM1 rs3179089 polymorphism with CAD is unknown. Objective: This study aimed to identify the relationship of CALM1 rs3179089 polymorphism with CAD susceptibility, CALM1 expression, blood pressure, blood glucose, blood coagulation and serum lipid levels of CAD patients. Methods: 550 CAD patients and 550 control subjects were genotyped for CALM1 using Sequenom MassARRAY technology. CALM1 expression level was measured by quantitative real time polymerase chain reaction (qRT-PCR). Results: CALM1 mRNA expression was higher in CAD patients than that in control subjects (P < 0.001). CAD patients with CC genotype had higher CALM1 mRNA expression level than control subjects with CC genotype (P = 0.006). Genotypic frequency of rs3179089 was different between male patients of CAD and control subjects (P = 0.045). Rs3179089 polymorphism was related to CAD risk of males in recessive model (P = 0.039). Moreover, rs3179089 polymorphism was associated with systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (FPG), and D-Dimer (D-D) level of patients with CAD in recessive model (P = 0.013 for SBP; P = 0.034 for DBP; P = 0.004 for FPG; P = 0.046 for D-D). In addition, rs3179089 polymorphism was correlated with low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) serum levels of patients with CAD in both addictive (P = 0.025 for LDL-C; P = 0.001 for TC) and recessive models (P = 0.001 for LDL-C; P = 0.001 for TC). Conclusion: CALM1 expression is associated with development of CAD. CALM1 rs3179089 polymorphism affects CAD susceptibility in males, and blood pressure, blood glucose, blood coagulation and serum lipid of CAD patients.
