Due to deficiency of Vitamin B12.
The inherited forms of methylmalonic acidemia cause defects in the metabolic pathway where methylmalonyl-coenzyme A (CoA) is converted into succinyl-CoA by the enzyme methylmalonyl-CoA mutase.
Vitamin B12 is also needed for the conversion of methylmalonyl-CoA to Succinyl-CoA. Mutations leading to defects in vitamin B12 metabolism or in its transport frequently result in the development of methylmalonic acidemia.
Add Answer to:
Methylmalonic acidemia is an autosomal recessive metabolic disorder in patients with elevated levels of methylmalonic acid....

6 In the condition hyperthyroidism, patients have elevated levels of both T3 and T4 due to a malfunction of the immune system that causes the thyroid gland to overproduce thyroid hormones. Do you think the negative feedback loops would lead to high levels of TSH or low levels of TSH? Explain. 16 90 In case 3 of Exercise 16-4 (p. 437), we saw that Professor Purple had insufficient antidiuretic hormone (ADH). However, the opposite condition can also occur in which...

1 a) A sudden increase in lactic acid levels during exercise can lead to metabolic acidosis. Acidosis is commonly treated by administering NaHCO, intravenously. Using the bicarbonate-carbon dioxide buffer system, qualitatively explain the effect of this procedure on blood pH. [6 points) b) The phosphate buffer system is another buffer system in the blood. Phosphates are found in the blood in two forms: sodium dihydrogen phosphate (Na2H2PO4), which is a weak acid, and sodium monohydrogen phosphate (Na2HPO 2), which is...

(1.5 pts.) Patients with Congenital Disorder of Glycosylation (for example, "CDG type Ia” or “CDG-Ia”), an inherited disease, can have a wide range of symptoms all caused by having mutations that affect the transfer of carbohydrates to proteins. Their inability to produce properly glycosylated proteins especially affects secreted proteins and those found on the cell surface. Deficiencies in these proteins lead to mental retardation, seizures, and liver disease. Which two organelles are most likely affected in these patients? Briefly explain...

1. Tay-Sachs is an autosomal recessive disorder, which is the inability for infants to breakdown gangliosides in the CNS, which overtime build-up and destroy neurons. As the disease progresses, the child loses muscle control. Eventually, this leads to blindness, paralysis and death. If you have a family history of Tay-Sachs disease or if you're a member of a high-risk group and plan to have children, doctors strongly recommend genetic testing and genetic counseling. Scott and Tina are a young couple...
