What causes Alstrom syndrome?
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.
Diagnosis
An eye doctor (ophthalmologist) will examine the eyes. The patient may have reduced vision.
Tests may be done to check:

- Hearing
- Heart function
- Thyroid function
- Triglyceride levels
When to seek urgent medical care?
Call your health care provider if you or your child have symptoms of diabetes such as increased thirst and urination. Seek medical attention promptly if you think that your child cannot see or hear normally.
