Familial encephalopathy with neuroserpin inclusion bodies

What it is

A rare serpinopathy characterized by progressive myoclonus epilepsy and/or pre-senile dementia with prominent frontal-lobe features and relative sparing of recall memory. In addition, other neurological manifestations like cerebellar symptoms and pyramidal signs may be present. Age of onset is variable, the disease having been reported in children as well as elderly patients. Neuropathological examination reveals the typical neuronal inclusions of mutated neuroserpin (Collins bodies).

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Genes reported in subtypes

Orphanet records this gene on 1 more specific entry 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.
