What it is
A rare genetic systemic disease characterized by adult onset, progressive sensorimotor and autonomic neuropathy and infiltrative cardiomyopathy. Neurological involvement usually starts with sensory loss in the extremities and progresses with motor neuropathy. Cardiomyopathy presents with rhythm abnormalities and heart failure. The disease also frequently manifests with a range of additional clinical signs and symptoms due to associated ocular, renal, central nervous system and gastrointestinal involvement.

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.
Genes reported in subtypes
Orphanet records this gene on 2 more specific entries under this disorder, not on this entry itself:
A well-studied disease is usually split into subtypes, and the gene is curated on whichever one the evidence belongs to. Open a subtype to see which gene goes with it.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
