Stroke after cardiac surgery in a patient with Smith-Magenis syndrome

Area of Science:

• Genetics
• Cardiology
• Neurology

Background:

• Smith-Magenis syndrome is associated with a high rate of congenital heart disease requiring surgical intervention.
• Genetic deletions in Smith-Magenis syndrome can impact cholesterol homeostasis.
• A link between Smith-Magenis syndrome, cholesterol metabolism, and premature atherosclerosis has not been previously established.

Observation:

• A patient with Smith-Magenis syndrome underwent cardiac surgery for congenital heart disease.
• Following surgery, the patient experienced a stroke.

Findings:

• The stroke is believed to be caused by premature intracerebral atherosclerosis.
• This suggests a potential association between Smith-Magenis syndrome-related gene deletions, cholesterol dysregulation, and early-onset atherosclerosis in cerebral vessels.

Implications:

• This case highlights a potential, previously unrecognized complication in Smith-Magenis syndrome patients undergoing cardiac surgery.
• Further research is warranted to explore the relationship between genetic factors affecting cholesterol homeostasis and atherosclerosis in this population.
• Understanding this link may inform preventative strategies and improve long-term outcomes for patients with Smith-Magenis syndrome.
