The 2373insG mutation in the MYBPC3 gene is a founder mutation, which accounts for nearly one-fourth of the HCM cases in the Netherlands

Aims Hypertrophic cardiomyopathy (HCM) is caused by mutations in genes that encode sarcomeric proteins. In this study we investigated the involvement of the sarcomeric myosin binding protein C in the Dutch HCM population. Methods and results We initially screened 22 Dutch index patients for mutations in the MYBPC3 gene, which revealed four different mutations in 14 patients. The 2373insG mutation was identified in 10 apparently unrelated patients. A subsequent screening for the 2373insG mutation in a group of another 237 unrelated HCM patients revealed 50 additional carriers of the same geneti... Mehr ...
