Alpha-mannosidosis is an "autosomal recessive metabolic disorder" that leads to physical and mental deterioration. When the a-mannosidase enzyme becomes defective, it causes impaired cell function and sugar buildup. Since this enzyme normally helps in breaking down complex sugars, absence of this functional enzyme may lead to death on children caused by deterioration of the central nervous system.
Alpha-mannosidosis occurs in 1 in 500,000 worldwide. This disease is found in all ethnic groups in America, Asia, Africa and Europe.
Diagnosis is made by measuring the enzyme activity in white blood cells and measuring substances in urine. Although diagnosis is usually made late, symptoms are often mild. However, biochemical diagnosis is difficult, so most cases are under diagnosed.
