Cerebrotendinous xanthomatosis (CTX) is a rare genetic disorder. This case report details a 23-year-old female patient with CTX, highlighting early-onset symptoms and elevated cholestanol levels.

Area of Science:

  • Biochemistry
  • Genetics
  • Neurology

Background:

  • Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive disorder of bile acid synthesis.
  • It results from mutations in the CYP27B1 gene, leading to impaired mitochondrial respiration and cholesterol metabolism.

Observation:

  • A 23-year-old female presented with xanthoma masses on knees, heels, and nasal bridge since age 8.
  • Clinical manifestations included juvenile cataracts, neurological dysfunction, and dementia.

Findings:

  • Elevated levels of cholestanol were detected in urine, serum, and xanthoma tissues.
  • Capillary gas chromatography confirmed the increased cholestanol levels, a hallmark of CTX.

Implications:

  • Early diagnosis and management of CTX are crucial to prevent irreversible neurological damage.
