About Methylmalonic acidemia with homocystinuria, type cblC

What is Methylmalonic acidemia with homocystinuria, type cblC?

Methylmalonic acidemia with homocystinuria, type cblC is a rare, inherited metabolic disorder caused by a deficiency of the enzyme methylmalonyl-CoA mutase. This enzyme is responsible for breaking down certain proteins and fats in the body. Without it, the body cannot properly process these proteins and fats, leading to a buildup of toxic substances in the blood. Symptoms of this disorder can include developmental delays, seizures, vision problems, and intellectual disability. Treatment typically involves a combination of dietary changes, vitamin supplements, and medications.

What are the symptoms of Methylmalonic acidemia with homocystinuria, type cblC?

The symptoms of Methylmalonic acidemia with homocystinuria, type cblC can vary from person to person, but may include:

-Developmental delay

-Intellectual disability

-Seizures

-Feeding difficulties

-Vomiting

-Failure to thrive

-Weak muscle tone

-Growth retardation

-Abnormal movements

-Behavioral problems

-Hearing loss

-Vision problems

-Kidney problems

-Liver problems

-Heart problems

-Skeletal abnormalities

-Skin rashes

-Thin hair

-High levels of methylmalonic acid and homocysteine in the blood

What are the causes of Methylmalonic acidemia with homocystinuria, type cblC?

Methylmalonic acidemia with homocystinuria, type cblC is caused by mutations in the MMACHC gene. This gene provides instructions for making an enzyme called methylmalonyl-CoA mutase. This enzyme is involved in breaking down certain proteins and fats in the body. Mutations in the MMACHC gene reduce or eliminate the activity of this enzyme, leading to a buildup of certain substances in the body, including methylmalonic acid and homocysteine. This buildup can cause the signs and symptoms of methylmalonic acidemia with homocystinuria, type cblC.

What are the treatments for Methylmalonic acidemia with homocystinuria, type cblC?

1. Dietary management: A low-protein diet is recommended to reduce the amount of methylmalonic acid produced in the body.

2. Vitamin B12 supplementation: Vitamin B12 is essential for the metabolism of methylmalonic acid and is often prescribed in the form of intramuscular injections.

3. Folic acid supplementation: Folic acid is important for the metabolism of homocysteine and is often prescribed in the form of oral supplements.

4. Betaine supplementation: Betaine is an amino acid that helps to reduce the levels of methylmalonic acid in the body.

5. Enzyme replacement therapy: Enzyme replacement therapy is used to replace the missing enzymes in the body that are responsible for the metabolism of methylmalonic acid and homocysteine.

6. Liver transplantation: In some

Is there a cure/medications for Methylmalonic acidemia with homocystinuria, type cblC?

Yes, there is a cure for Methylmalonic acidemia with homocystinuria, type cblC. Treatment typically involves a combination of dietary modifications, vitamin supplements, and medications. Dietary modifications may include a low-protein diet and supplementation with carnitine, taurine, and other amino acids. Vitamin supplements, such as B12, folate, and pyridoxine, may also be prescribed. Medications such as betaine, hydroxycobalamin, and cobalamin may be prescribed to help reduce levels of methylmalonic acid in the blood.
