An autopsy case of gallbladder cancer developing in a Japanese man with cerebrotendinous xanthomatosis: genetic analysis of the sterol 27-hydroxylase and p53 genes.
Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive lipid-storage disorder characterised by xanthomas, neurological dysfunctions and premature atherosclerosis. A case of a well differentiated adenocarcinoma of the gallbladder occurring in a 57-year-old Japanese man with CTX, confirmed clinically, biochemically and at autopsy is reported together with analyses of the sterol 27-hydroxylase (CYP27) and p53 genes. A missense mutation of the p53 (G for C) was detected in the gallbladder adenocarcinoma. Direct sequence analysis also showed a silent mutational substitution of unknown significance, C for A, in CYP27 at codon 89. In the past, CTX patients have only demonstrated this infrequently, indicating no direct relationship between CYP27 dysfunction and tumour development. Thus, the present case of gallbladder cancer appears to be a chance occurrence.
