Conditions

Definition

Alström syndrome is a very rare disease passed down through families (inherited) that can lead to blindness, deafness, diabetes, and obesity.

Causes, incidence, and risk factors

Alström syndrome is inherited in an autosomal recessive manner. This means both your parents must pass on a copy of the defective gene (ALMSI) in order for you to have this disease.

It is unknown how the defective gene causes the disorder.

The condition is extremely rare. It is more common in Holland and Sweden than in the United States.
