Familial chylomicronemia syndrome

Area of Science:

• Biochemistry
• Genetics
• Metabolic Disorders

Background:

• Familial chylomicronemia syndrome (FCS) is a rare genetic disorder affecting lipoprotein metabolism.
• It results from deficiencies in lipoprotein lipase (LPL) or apolipoprotein C-II, or LPL inhibitors.
• FCS leads to severe hypertriglyceridemia and chylomicronemia.

Observation:

• The study presents two siblings diagnosed with familial chylomicronemia syndrome.
• Clinical manifestations included eruptive xanthomas and acute pancreatitis.
• Laboratory findings revealed markedly elevated triglyceride and chylomicron levels, characteristic of lipaemic plasma.

Findings:

• The siblings' condition is attributed to familial lipoprotein lipase deficiency.
• This case illustrates the characteristic clinical and biochemical phenotype of FCS.
• Literature review supports the rarity and typical presentation of this disorder.

Implications:

• Early diagnosis and management of FCS are crucial to prevent severe complications like pancreatitis.
• Understanding the genetic basis of FCS aids in family screening and genetic counseling.
• This report contributes to the literature on rare lipoprotein disorders and their clinical impact.
