BAG3 (O95817) variants and mutations

BAG3 (also known as O95817) is a human protein-coding gene encoding a BAG family molecular chaperone regulator 3 protein. It coordinates chaperone-assisted protein quality control and autophagy, particularly in mechanically stressed cardiac and skeletal muscle. Pathogenic variants can impair sarcomere maintenance and cause dilated cardiomyopathy or myofibrillar myopathy. This analysis covers 1,223 BAG3 variants and mutations. Of these, 80% have computational variant effect predictions. Disease context includes dilated cardiomyopathy 1HH, myofibrillar myopathy 6, and dilated cardiomyopathy. Example BAG3 variants include M1?, M1L, and M1R.
