Occurrence/EpidemiologyThis section has been translated automatically.
The incidence of Alström syndrome is 1: 1,000,000, making it a very rare condition (Braune 2017).
EtiopathogenesisThis section has been translated automatically.
Autosomal recessive inheritance with mutation at gene ALMS1 (Herold 2021)
Clinical featuresThis section has been translated automatically.
In infancy, nystagmus, photophobia and macular degeneration already occur (Danne 2016).
Otherwise, a broad spectrum of clinical manifestations is found, such as:
- diabetes mellitus type 2
- retinopathy (Herold 2021)
- sensorineural hearing loss (Schmidt 2006)
Variable manifestation concern:
- chronic hepatitis
- bronchial asthma (Baumeister 2003)
DiagnosticsThis section has been translated automatically.
Based on the typical constellation of symptoms (Berwanger 2002) and by genetic testing (Braune 2017).
Differential diagnosisThis section has been translated automatically.
Laurence-Moon-Bardet- Biedl- Syndrome (Berwanger 2002)
TherapyThis section has been translated automatically.
Treatment is carried out according to the respective concomitant diseases.
Rosiglitazone is one of the drugs that can be used. This leads to an improvement in the HbA1c concentration, a decrease in serum triglycerides and an improvement in elevated transaminases (Schmidt 2006).
Progression/forecastThis section has been translated automatically.
Life expectancy is limited and is approximately 50 years (Braune 2017).
