Familial benign copper deficiency

Familial benign copper deficiency, also known as Familial benign hypocupremia is a rare genetic disorder which is characterized by hypocupremia that causes symptoms such as epilepsy, hypotonia, seborrheic skin, thriving failure and mild anemia. Radiological findings include tibia and femur spurring. Transmission is thought to be either autosomal dominant or X-linked dominant.
Symptoms are caused by a familial tendency of having low levels of copper within the body and can be improved with oral supplements of copper.
It has been described in members of a 3-generation Hungarian family.
