What are the best treatments for Alström syndrome?

There is currently no cure for Alström syndrome; therefore, treatment focuses on a multidisciplinary approach to manage the diverse, multi-systemic symptoms that arise over time. Care is primarily supportive, involving early intervention for vision and hearing loss, metabolic monitoring for type 2 diabetes and obesity, and regular surveillance of cardiac and renal function.

How is Alström syndrome managed medically?

Because Alström syndrome is a rare, multisystem genetic disorder, there is no single "first-line" medication. Instead, treatment is highly individualized based on the specific organ systems affected. For patients with Alström syndrome, the management of metabolic issues is often the highest priority. This includes standard therapies for type 2 diabetes, such as metformin or insulin, and the management of hyperinsulinemia. Because obesity is a hallmark feature, physicians may monitor patients closely for metabolic syndrome and non-alcoholic fatty liver disease (NAFLD).

What non-pharmacological interventions are recommended?

Non-pharmacological support is the cornerstone of quality of life for those living with Alström syndrome. Because the disease leads to progressive rod-cone dystrophy and sensorineural hearing loss, early access to assistive technologies is essential. The following strategies are vital components of a comprehensive care plan:

• Vision support: Early referral to low-vision specialists for orientation, mobility training, and the use of adaptive devices.


• Audiological care: Regular hearing assessments and timely fitting of hearing aids or cochlear implants.


• Physical and Occupational Therapy: Essential for addressing developmental delays in children and maintaining motor function as the disease progresses.


• Cardiac monitoring: Dilated cardiomyopathy is a significant risk in Alström syndrome, necessitating regular echocardiograms and management by a pediatric cardiologist.


• Endocrine surveillance: Strict monitoring of thyroid function, as hypothyroidism is frequently associated with the condition.

Are there emerging treatments or clinical trials?

Research into Alström syndrome is ongoing, with a focus on understanding the underlying cellular mechanisms of the ALMS1 gene mutation. While no gene therapy is currently approved, researchers are investigating metabolic modulators and anti-fibrotic agents that may help mitigate the systemic damage caused by the syndrome. Patients are encouraged to consult resources like ClinicalTrials.gov to stay informed about active studies investigating the natural history or potential therapeutic interventions for Alström syndrome.

Which specialists should be on the care team?

Given the complexity of Alström syndrome, a multidisciplinary team is necessary to provide comprehensive care. This team should ideally be coordinated by a clinical geneticist and include pediatric or adult specialists in cardiology, endocrinology, ophthalmology, audiology, nephrology, and gastroenterology. At DiseaseMaps.org, 45 people with Alström syndrome have joined our community, highlighting the value of connecting with others who navigate these complex medical journeys.

Next steps

• Consult with a clinical geneticist to confirm the diagnosis and discuss family screening.


• Establish a primary care coordinator to facilitate communication between the various specialists on your care team.


• Join a patient advocacy organization, such as the Alström Syndrome International, to access resources and connect with others.


• Participate in patient registries to contribute to the global understanding of the disease progression.
