Absent in Melanoma 2 Gene Associated Periodontitis and Coronary Heart Disease.

Aims: To study the association between AIM2 gene polymorphisms and the tendency for periodontal infection and coronary heart disease, and to determine whether males or females are more susceptible to these diseases. Additionally, we examined its association with the features of periodontal disease. Methods: 140 patients were enrolled in this study, and those who took part were divided into four groups as follows: healthy (c), periodontal disease (P), coronary heart disease with intact periodontium (AS-C), and coronary heart disease with periodontal disease (AS-P). Information on entrants, including age ranging from 40 to 70 years old, sex of both males and females who fulfilled the study's criteria, body mass index with ordinary rang less than 30 kg/m 2, socioeconomic status, tooth brushing frequency at least two times per- day, and indicators of periodontal disease severity, was documented. Blood samples were collected, and AIM2 gene polymorphisms were evaluated by polymerase chain reaction test, gel phase, and sequences. Results: Genetic analysis of AIM2 G/T (rs 2793845) revealed a high frequency of the (T) allele and (GT and TT) genotypes that were detected in the periodontal disease and coronary heart disease groups in males. The Hardy-Weinberg equilibrium of alleles and genotypes did not differ significantly (p > 0.05) between the study groups. Gene polymorphisms were also significantly (p ≤ 0.05) correlated with indicators of periodontal disease severity. Conclusion: High frequenting of (T) alleles and (GT, TT) genotypes in AIM2 single nucleotide polymorphisms (SNP) were associated with an increased tendency to develop periodontal disease and coronary heart disease. It can be supposed that it has a causative function in the pathophysiology of both disorders, and the validity of SNP as a potential genomic factor for the risk of both disorders in Iraqi males.
