Saffitz, M.D., Ph.D.: A New Diagnostic Test for Arrhythmogenic Best Ventricular Cardiomyopathy Arrhythmogenic right ventricular cardiomyopathy is usually associated with a high frequency of arrhythmias and unexpected cardiac death.1-3 Mutations in genes encoding desmosomal proteins have already been identified in approximately 40 percent of individuals with ARVC.4 However, genetic analysis remains a extensive research tool, and in everyday practice, the medical diagnosis of ARVC can be challenging.

We attained fibroblast specimens from four handles and from Subject II-2 in Family 1. We obtained written informed consent from the affected people and their family members and written informed consent from the controls. The institutional review board of Niigata University approved this scholarly study. Assay of HTRA1 Protease Activity Expressing HTRA1 in Escherichia coli simply because fusions with glutathione S-transferase, we subcloned wild-type or mutant HTRA1 complementary DNA , lacking codons 1 through 140, in to the vector pGEX 6P-3 . The N-terminus of HTRA1 is normally toxic to E. Coli. Amino acid substitution of the serine protease motif S328A, which abolishes the protease activity in HTRA1, was used as a negative control.14 Glutathione S-transferase fusion proteins had been purified and overexpressed.
