Aase syndrome or Aase–Smith syndrome is a rare inherited disorder characterized by anemia with some joint and skeletal deformities. Aase syndrome is thought to be an autosomal recessive inherited disorder. The genetic basis of the disease is not known. The anemia is caused by underdevelopment of the bone marrow, which is where blood cells are formed.
It is named after the American paediatricians Jon Morton Aase and David Weyhe Smith, who characterized it in 1968.
As with most genetic diseases there is no way to prevent the entire disease. With prompt recognition and treatment of infections in childhood, the complications of low white blood cell counts may be limited.
Frequent blood transfusions are given in the first year of life to treat anemia. Prednisone may be given, although this should be avoided in infancy because of side effects on growth and brain development. A bone marrow transplant may be necessary if other treatment fails.
Anemia usually resolves over the years.
