Homocystinuria with Epilepsy

Treatment of Homocystinuria with Pyridoxine

Homocystinuria is the result of an inborn error in the metabolism of the essential sulphur-containing amino acid, methionine (Carson and Neill, 1962; Gerritsen, Vaughn, and Waisman, 1962). There is now good evidence (Mudd et al., 1964) to show that the basic defect in this disorder is an inactivity of hepatic cystathionine synthetase, which prevents the formation of cystathionine from homocyste...

Homocystinuria and Marfan’s Syndrome

Dystonia in homocystinuria.

Three patients with homocystinuria due to cystathionine beta-synthase deficiency who developed progressive generalised dystonia are described. Although cerebrovascular thrombosis is usually thought to be responsible for neurological dysfunction in homocystinuric patients, neuropathological studies in one case and clinical and radiological evidence in the other two suggested that dystonia was no...

Pathological Findings in Homocystinuria.

Pathological findings are described in four cases of a new aminoaciduria in which homocystine is excreted in the urine. All the patients were mentally retarded children. Three of them presented diagnostic features of Marfan's syndrome. Necropsy on one case and biopsy findings in the others are described. Fatty change occurs in the liver. The most striking lesions are vascular. Metachromatic med...
