Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if simvastatin improves development and behavior in patients with Smith Lemli-Opitz syndrome (SLOS) receiving dietary cholesterol supplementation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with SLOS receiving dietary cholesterol supplementation are given simvastatin, a drug that decreases the activity/expression of HMG-CoA reductase, an enzyme that controls the first step of the cholesterol synthesis pathway, reduces the accumulation of toxic 7-dehydrocholesterol (immediate metabolic precursor of cholesterol) and improve neurocognitive and behavioral outcomes.
