BACKGROUND
Molybdenum cofactor deficiency (MOCD) is a severe autosomal recessive neonatal metabolic disease that causes seizures and death or severe brain damage. Symptoms, signs and cerebral images can resemble those attributed to intrapartum hypoxia. In humans, molybdenum cofactor (MOCO) has been
Homocystinuria is a rare autosomal recessive disorder of amino acid metabolism. Classic (type I) homocystinuria is the most common type and occurs as a consequence of a deficiency of cystathionine-b-synthase, producing increased blood and urine homocysteine. The authors report a 15-year-old Thai
BACKGROUND
Homocystinuria caused by cystathionine beta synthase (CBS) deficiency is most often diagnosed in childhood and has a variable expressivity. The most frequent abnormalities include intellectual disability, ectopia lentis, myopia, skeletal abnormalities or thromboembolism.
OBJECTIVE
To
Homocystinuria with elevated plasma homocysteine and methionine levels is the result of deficient activity of cystathionine synthetase, the enzyme catalyzing conversion of homocysteine to cystathionine. It is inherited as an autosomal recessive trait with a worldwide distribution. The major clinical
Homocystinuria is an inborn error of methionine metabolism, of which cause is mainly deficiency of cystathionine synthetase. The major clinical manifestations of homocystinuria are mental retardation, seizures, ectopia lentis, skeletal deformities and occlusive vascular disease. A case of
Objective Homocystinuria is an inborn error of amino acid metabolism caused by cystathionine beta-synthase deficiency that affects methionine metabolism. The clinical features are heterogeneous ranging from mental retardation, ectopia lentis, and osteoporosis to vascular events such as deep vein
We explored the clinical and molecular characteristics of molybdenum cofactor deficiency due to MOCS2 muations.We summarize the genetic and clinical findings of previously reported patients with a MOCS2 mutation. We also present a new patient with novel We report the clinical, biochemical, neuroradiological, and neurophysiological findings of a 4-year-old Chinese girl with infantile isolated sulphite oxidase deficiency. This is the first reported case in our locality. She presented at the age of 5 months with refractory seizures and developmental
The amino acid homocysteine (Hcy), formed from methionine has profound importance in health and diseases. In normal circumstances, it is converted to cysteine and partly remethylated to methionine with the help of vit B12 and folate. However, when normal metabolism is disturbed, due to deficiency of
OBJECTIVE
The authors describe two cases of isolated sulfite oxidase deficiency found in one family. This is a rare autosomal-recessive disorder presenting at birth with seizures, severe neurologic disease, and ectopia lentis. It can be easily missed with metabolic screening; however, the finding of
BACKGROUND
Classic homocystinuria is an autosomal recessive disorder due to cystathionine ss-synthase deficiency. The clinical, radiological and neurophysiological findings of classic homocystinuria diagnosed at King Faisal Specialist Hospital and Research Centre (KFSH&RC) are presented in this
BACKGROUND
Sulfite oxidase deficiency (SOD) is an autosomal recessive inherited disease usually presenting in the neonatal period with severe neurological symptoms including seizures, often refractory to anticonvulsant therapy, and a rapidly progressive encephalopathy resembling neonatal hypoxic
Isolated sulfite oxidase deficiency (ISOD) is a life-threatening, autosomal recessive disease characterized by severe neurological impairment. As no long-term effective treatment is available, distinction from other treatable diseases, such as molybdenum cofactor deficiency (MoCD) type A, should be
Isolated sulfite oxidase deficiency (ISOD) is a rare autosomal recessively inherited inborn error of metabolism, caused by mutation in SUOX gene. ISOD has two kind of presentation; early and late-onset. The late-onset form is extremely rare and only 10 cases have been Isolated sulfite oxidase deficiency is a rare but devastating neurologic disease that usually presents in early infancy with seizures and alterations in muscle tone. Only 21 cases have been reported in the literature. We report a case of a newborn infant boy with isolated sulfite oxidase deficiency
