Many of these studies use a p-value of 5*10− 8, which allows us to find a stronger linkage, but many studies have different results, only repeating genes are HCG22, BAG3, and HSPB7. Applying new techniques, such as long-read sequences, allows alignment to more complete human genomes [37] and having more uniform biobanks with control cases will allow us to better understand the heterogeneity of DCM. This evidence concerns the gene HCG22 and familial dilated cardiomyopathy.
