Hereditary sensory and autonomic neuropathy type II (HSAN II) leads to severe mutilations because of impaired nociception and autonomic dysfunction. Here we show that loss-of-function mutations in FAM134B, encoding a newly identified cis-Golgi protein, cause HSAN II. Fam134b knockdown results in structural alterations of the cis-Golgi compartment and induces Apoptosis in some primary dorsal root ganglion neurons. This implicates FAM134B as critical in long-term survival of nociceptive and autonomic ganglion neurons.
