EtiopathogenesisThis section has been translated automatically.
Autosomal recessive inheritance. Relatively frequent occurrence in Jewish Sephardic families of Moroccan origin. Two mutations are known in the C27 hydroxylase gene (CYP27 and CTX), which is located at the distal end of the long arm on chromosome 2 (2q33-qter). The gene encodes the mitochondrial cytochrome P 450 of subfamily 27 and the sterol 27 hydroxylase. The enzyme defect leads to a disturbance of bile acid synthesis and accumulation of cholestanol. The vitamin D metabolism can also be disturbed by the enzyme defect.
Clinical featuresThis section has been translated automatically.
Multiple tendon xanthomas already in childhood. Normal plasma cholesterol concentration. Increase of the plasma molestanol concentration. Premature cataract. Dementia. Pyramidal trajectory signs. Cerebellar ataxia. Bulbar paralysis. Premature atherosclerosis. Possible osteoporosis.
Differential diagnosisThis section has been translated automatically.
Differentiation from other diseases with early tendon exanthomas by determination of plasma cholesterol and, if applicable, LDL receptors on monocytes (familial hypercholesterolemia), by determination of the Apo-E phenotype (familial hyperlipoproteinemia type III) and by determination of plant sterols in serum (sitosterolemia with xanthomatosis).
TherapyThis section has been translated automatically.
Early therapeutic use of chenodesoxycholic acid can prevent the development of neurological symptoms.
