Aase syndrome is a rare disorder that involves anemia and certain joint and skeletal deformities.
Most cases of Aase syndrome occur without a known reason and are not passed down through families (inherited). However, some cases have been shown to be inherited as an autosomal dominant and autosomal recessive traitn.
The anemia associated with Aase syndrome is caused by underdevelopment of the bone marrow, which is where blood cells are formed.
