Hereditary sensory and autonomic neuropathy due to TECPR2 mutation

What it is

A rare genetic peripheral neuropathy characterized by early hypotonia evolving to spastic paraparesis, areflexia, decreased pain and temperature sensitivity, autonomic neuropathy, gastroesophageal reflux disease, recurrent pneumonia and respiratory problems. Patients also have intellectual disability and dysmorphic features, including mild brachycephalic microcephaly, short broad neck, low anterior hairline and coarse face.

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.

Signs and symptoms

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.
