To date, three cases have been described.
Two patients presented with a rigid spine and one a peripheral neuropathy. Disintegration of Z disks, extensive accumulation of granular debris and larger inclusions, and apoptosis of a small fraction of the nuclei characterize the disease.
The disease is due to a mutation in the BAG3 gene, encoding a protein localized to the Z disk.
Transmission is autosomal dominant.
