Cerebrotendinous xanthomatosis (CTX) is a rare metabolic disease with autosomal recessive inheritance. It is caused by mutations of the CYP27A1 gene, which codifies for sterol 27-hydroxylase, an enzyme that is responsible for the synthesis of cholic acids. In CTX, cholic acid synthesis is impaired, Cerebrotendinous xanthomatosis (CTX) is an uncommon genetic disorder with an autosomal recessive inheritance. [ 1] It is a lipid storage disorder caused by mutations in the CYP27A1 gene, located on chromosome 2q33 which is responsible for encoding sterol-27 hydroxylase, prime enzyme for bile acid biosynthesis.

Neurocutaneous Disorders - January 200 Cerebrotendinous xanthomatosis, while not strictly a neurocutaneous disease, is a unique disorder in which remote biochemical mischief produces progressively devastating effects upon the nervous system. Simultaneously with the development of these nervous system lesions, prominent tendon xanthomas develop, affording early students of this.

Xanthomas are the result of lipomatosis seen in inherited metabolic diseases such as type 2 and type 3 hyperpoproteinemias and cerebrotendinous xanthomatosis .

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive disease, due to a deficiency of sterol 27-hydroxylase (CYP 27), a key enzyme in the synthesis of chenodeoxycholic acid (CDCA), a primary bile acid. In CTX, deficiency of CYP 27 and thus a lack of CDCA leads to the storage of cholestanol and cholesterol in many tissues, especially.
Abstract. Cerebrotendinous xanthomatosis (CTX) is a rare and treatable autosomal recessive disease. The diagnosis should be suspected in the presence of a suggestive clinical triad characterized by early-onset cataract, tendinous xanthomata and neurological symptoms and signs, notably cerebellar ataxia, mental retardation and pyramidal syndrome.The diagnosis is confirmed by demonstrating an. 1259 SHORT COMMUNICATION Cerebrotendinous Xanthomatosis with Cerebellar Ataxia as the Chief Symptom HirohisaOkuma1,YasuhisaKitagawa2,KentaroTokuoka2 andShigeharuTakagi3 Key words: cerebrotendinousxanthomatosis,cerebellar ataxia (DOI: 10.2169/internalmedicine.46.6448 Cerebrotendinous xanthomatosis (CTX) is a treatable, autosomal-recessive, multisystemic lipid storage disorder with various neuro- 5Department of Radiology, Xuanwu Hospital of Capital Medical University, Beijing, China; 6National Clinical Research Center for Geriatric Disorders, Beijing, Chin Barkhof F, Verrips A, Wesseling P, van Der Knaap MS, van Engelen BG, Gabreëls FJ, et al.

Often referred to as CTX, cerebrotendinous xanthomatosis is a rare inherited condition present from birth. Those with this condition develop an excessive amount of fat in multiple organs throughout the body, interfering with proper functioning and resulting in a variety of health problems. This abnormal collection of fat is particularly prominent [
