Cholesterol levels in fragile X syndrome

Area of Science:

• Neurogenetics
• Metabolic Disorders
• Clinical Medicine

Background:

• Fragile X syndrome (FXS) presents with intellectual disability and behavioral issues.
• Long-term health data, particularly metabolic profiles, for adults with FXS is scarce.
• Previous observations suggested low cholesterol in FXS patients.

Purpose of the Study:

• To systematically investigate lipid profiles, specifically cholesterol levels, in a large cohort of adult males with FXS.
• To compare these lipid values against age-adjusted population norms.
• To assess the clinical relevance of these findings for FXS management and research.

Main Methods:

• A retrospective chart review was conducted on over 500 patients with FXS.
• Total cholesterol (TC), low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels were extracted.
• Data was compared to age-adjusted normative values for the general population.

Main Results:

• Males with FXS exhibited significantly reduced levels of TC, LDL, and HDL compared to controls.
• These findings were consistent across the large FXS cohort.
• No prior systematic data on cholesterol in FXS adults was available.

Conclusions:

• Adult males with FXS have significantly lower cholesterol and HDL levels than the general population.
• These lipid alterations warrant consideration in the health monitoring of individuals with FXS.
• The findings may inform therapeutic strategies targeting CNS pathways in FXS and aid in biomarker development.
