Premature termination codon at the sterol 27-hydroxylase gene causes cerebrotendinous xanthomatosis in a French family.
Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive lipid-storage disease caused by mutations in the sterol 27-hydroxylase gene (CYP27). So far several mutations causing CTX have been identified and characterized. A new mutation creating an insertion of cytosine at position 6 in the cDNA, which is expected to result in a frameshift and a premature termination codon at codon 179, has been identified in a French family. The mutation creates a new site for the restriction endonuclease HaeIII.
