| Background: Hypertrophic cardiomyopathy is a common genetic cardiovascular disease with autosomal dominant inheritance and MYBPC3 gene has been frequently linked to its pathogenesis. Since, carriers of the 25 nucleotides deletion located on intron 32 of the MYBPC3 are at increased risk of heart disease we aimed to investigate this variant in hypertrophic cardiomyopathy patients and healthy population. Methods: DNA was extracted from 350 Blood samples including 42 hypertrophic cardiomyopathies and 308 healthy subjects and the region containing the deletion was amplified by PCR method. PCR products were analyzed on agarose gel and genotyping results were recorded. Results: Genetic counseling results revealed that 26.2% of patients were sporadic cases vs 59.5% with positive family history and there was a history of sudden cardiac death in the first degree relatives of 42.3% of the patients. Genotyping results showed that all samples had a single band of 198 bp, indicating no MYBPC3Δ25bp variant in HCM patients as well as 308 controls. Bioinformatics assessments revealed that MYBPC3Δ25bp had a frequency of 0.00438 on Iranome database with the highest incidence reported in the Baloch population. Conclusion: Since hypertrophic cardiomyopathy is related to sudden cardiac death, population studies in terms of predisposing factors are of particular importance. Our study results showed that MYBPC3Δ25bpshould not be considered as risk factor in the patients of northwest of Iran. However, according to the bioinformatics findings and reports of neighboring countries, it is suggested that MYBPC3Δ25bp to be studied in the eastern and southern Iranian hypertrophic cardiomyopathy patients. |
