Investigation of genetic disorders affecting cholesterol synthesis

Investigations Into Inborn Errors of Cholesterol Synthesis and Related Disorders

National Institutes of Health Clinical Center (CC) · NCT00046202

This study is trying to learn more about genetic disorders that affect cholesterol production by collecting samples from people with these conditions and those who might carry them.

What this trial studies

This observational study focuses on understanding inborn errors of cholesterol synthesis, which can lead to various medical issues including birth defects and cognitive impairments. Participants with these genetic disorders, such as Smith-Lemli-Opitz syndrome and others, will provide blood, urine, and other tissue samples for analysis. The study aims to collect biomaterials and medical information to better understand the pathological processes associated with these rare conditions. Additionally, individuals suspected of having these disorders or those who are carriers may also participate.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with or suspected to have an inborn error of cholesterol synthesis or those related to such individuals.

Not a fit: Patients without any genetic disorders related to cholesterol synthesis or those not connected to affected individuals may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of cholesterol synthesis disorders, leading to improved diagnosis and management for affected patients.

How similar studies have performed: While this study addresses a rare group of disorders, similar studies have shown promise in understanding genetic metabolic conditions, though the specific focus on cholesterol synthesis is less commonly explored.
