Additional Information

Useful For​
  • Measuring plasma levels of Cholestanol, Cholesterol and 7-Dehydrocholesterol.
  • The level of cholestanol is diagnostic for the disorder Cerebrotendinous xanthomatosis. The build up of cholestanol in tendon and neural tissues causes ataxia, dementia and eventually death from the fourth decade. It is often associated with high plasma cholesterol.
  • Abnormal levels of 7-Dehydrocholesterol is diagnostic of the Smith-Lemi-Opitz syndrome.
​Clinical Indication ​Microcephaly, dysmorphic features, variable skeletal dysplasies, growth and mental retardation as well as heart and kidney defects. The most consistent clinical feature is 2nd and 3rd toes syndactyly.
