- Abstract
A patient is described with many clinical features of cerebrotendinous xanthomatosis (CTX), but with only slightly elevated cholestanol/cholesterol concentration ratios in serum and xanthomatous tissue. However, with capillary gas chromatographic determinations of urinary bile acids and bile alcohols we demonstrated the typical biochemical abnormalities as seen in CTX patients. This article emphasizes the value of urinary capillary gas chromatography as a specific test to establish the diagnosis of CTX and to monitor the biochemical effectivity of the different treatment regimens.
