Familial benign copper deficiency

What it is

Familial benign copper deficiency is a rare disorder of mineral absorption and transport characterized by hypocupremia that manifests as failure to thrive, mild anemia, repeated seizures, hypotonia, and seborrheic skin. Spurring of the femur and tibia are also noted on radiographic imaging. Symptoms are reversible or improve with supplements of oral copper. There have been no further descriptions in the literature since 1988.

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.
