What it is
A rare genetic, multisystemic lysosomal disease characterized by specific cutaneous (angiokeratoma), neurological (pain), renal (proteinuria, chronic kidney failure), cardiovascular (cardiomyopathy, arrhythmia), cochleo-vestibular and cerebrovascular manifestations (transient ischemic attacks, strokes). The phenotypic expression depends on age of onset and, in females, the level of X-inactivation.

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.

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.
