Presentation
Cardiac disease may be present in up to 33%. [emedicine.medscape.com]
Peripheral neuropathy is present in about 20% of affected individuals. Overt cardiomyopathy is present in 15%-30%. [ncbi.nlm.nih.gov]
Patients typically present thin, sclerotic muscles with a woody consistency, mild girdle and proximal limb weakness with moderate distal weakness and scoliosis. [orpha.net]
The onset usually occurs in adult life (between the second and fourth decade) but may be congenital or present in early childhood. [medlink.com]

In childhood, RCM accounts for 2–5% of cardiomyopathies and has a grave prognosis ( Kaski, 2008 .) [intechopen.com]
Etiology
Duygu Selcen [2] has identified a number of different etiologies including alpha-B-crystallin, filamin-C, FHL1, desmin, myotilin, plectin, ZASP, and BAG3. [link.springer.com]

We have proposed that protein aggregation is prevented by manipulation of the ER microenvironment with αBC, and have shed light on a novel aspect of the ER as a therapeutic target. [thebiogrid.org]
Abstract α-B-Crystallin (CryAB, gene map locus: 11q22.3-q23.1) is a member of the small heat shock protein (HSP) family, a group of proteins that prevent protein aggregation upon exposure of a cell to heat and/or restore the biological activity of cell [ncbi.nlm.nih.gov]
Has chaperone-like activity, preventing aggregation of various proteins under a wide range of stress conditions. [genecards.org]
