Sjögren-Larsson Syndrome Patient Resources

Living with Sjogren Larsson Syndrome


Sjögren-Larsson syndrome (SLS) is a rare genetic disease caused by mutations in the gene that encodes an enzyme called fatty aldehyde dehydrogenase. SLS smutation results in accumulation of fatty aldehydes (toxic chemicals) that are thought to cause severe ichthyosis (scaly, thickened, dry skin), neurological disorders (which may include spasticity, seizures, and cognitive delay), and, in some patients, retinal disease. 


National Organization for Rare Disorders

The National Organization for Rare Disorders (NORD), is a non-profit organization dedicated to helping people with rare diseases. Aldeyra and NORD are working to increase awareness of SLS and provide patients with opportunities to connect with each other and to access information about their disease and ongoing efforts related to diagnosis and treatment. 

SLS Network Community

Through the collaboration with NORD’s RareLaunch® program, NORD provides mentorship, encourages knowledge sharing, promotes networking, and supports the growth of a strong-independent rare disease patient organization.

The Sjögren-Larsson Syndrome Registry

The Sjögren-Larsson Syndrome Registry is a new database to accelerate research and cures for patients with this rare disease. The Registry creates a platform for patients around the world to share information about SLS with researchers. There are currently no FDA-approved treatments for SLS.   The SLS Registry is part of NORD’s registry program, which NORD developed with input from patients and patient organizations, researchers, and regulators as part of its mission to identify and treat all 7,000 rare diseases.

The Foundation for Ichthyosis & Related Skin Types, Inc.® (FIRST) is the world's leading patient advocacy organization dedicated to improving lives and seeking cures for those affected with ichthyosis or a related skin type. FIRST educates, inspires and connects all affected individuals, their families, medical professionals and the general public with regard to these specific sets of skin disorders. FIRST is also the only patient advocacy organization funding research in the field of treatments and cures for ichthyosis.

Reproxalap As A Potential Treatment For SLS 

We announced positive Phase 2 data from our randomized, vehicle-controlled, double-masked clinical trial of topical dermatologic reproxalap to treat the skin disease in patients with SLS. The skin of all reproxalap-treated patients improved, and the magnitude of improvement was statistically greater than that of vehicle-treated patients. The results of the clinical trial suggest that reproxalap could be the first mechanistically directed therapy in SLS.
