Congenital enterocyte heparan sulfate deficiency

What it is

A rare, severe, genetic, intestinal disease characterized by congenital absence of heparan sulfate from small intestine epithelium manifesting with secretory diarrhea and massive enteric protein loss. Patients present intolerance to enteral feeds during the first few weeks to months of life. Apart from absence of heparan sulfate from the basolateral surface of small intestine enterocytes, small bowel biopsy is otherwise normal.

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.

Related health topics

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