Case Report: Cerebrotendinous xanthomatosis.

Area of Science:

• Biochemistry
• Genetics
• Neurology

Background:

• Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive disorder.
• It is characterized by impaired bile acid synthesis due to mutations in the CYP27A1 gene.
• This leads to the accumulation of cholestanol and cholesterol in various tissues.

Observation:

• A 36-year-old woman presented with a constellation of symptoms.
• These included juvenile cataract, chronic diarrhea since childhood, cognitive impairment, and cerebellar ataxia.
• Physical examination revealed bilateral xanthomas on the Achilles tendons.

Findings:

• Radiological investigations provided insights into the extent of lipid deposition.
• Histopathologic examination of the xanthomas confirmed the diagnosis.
• The patient's presentation encompassed neurological, ophthalmological, and gastrointestinal manifestations.

Implications:

• This case underscores the importance of recognizing the diverse clinical spectrum of Cerebrotendinous xanthomatosis.
• Early diagnosis and management are crucial for mitigating neurological damage and improving patient outcomes.
• Further research into CTX pathogenesis and therapeutic strategies is warranted.
