About Combined oxidative phosphorylation defect type 2
What is Combined oxidative phosphorylation defect type 2?
Combined oxidative phosphorylation defect type 2 (COXPD2) is a rare genetic disorder caused by mutations in the SURF1 gene. It is characterized by a deficiency in the production of energy in the cells of the body, leading to a wide range of symptoms including muscle weakness, seizures, and developmental delays. It is inherited in an autosomal recessive pattern, meaning that both copies of the gene must be mutated in order for the disorder to be present. Treatment typically involves dietary modifications, physical therapy, and medications to manage symptoms.
What are the symptoms of Combined oxidative phosphorylation defect type 2?
The symptoms of Combined oxidative phosphorylation defect type 2 (COXPD2) vary depending on the severity of the condition, but may include:
- Poor feeding
- Muscle weakness
- Poor growth
- Developmental delay
- Seizures
- Cardiomyopathy
- Respiratory distress
- Liver dysfunction
- Hypoglycemia
- Hypotonia
- Lactic acidosis
- Hyperammonemia
- Mitochondrial dysfunction
What are the causes of Combined oxidative phosphorylation defect type 2?
Combined oxidative phosphorylation defect type 2 (COXPD2) is a rare genetic disorder caused by mutations in the SURF1 gene. Mutations in this gene lead to a deficiency in the production of cytochrome c oxidase (COX), an enzyme involved in the production of energy in the mitochondria. This deficiency results in a decrease in the production of ATP, the energy currency of the cell, leading to a wide range of symptoms. The exact cause of the mutations in the SURF1 gene is unknown, but it is believed to be inherited in an autosomal recessive pattern.
What are the treatments for Combined oxidative phosphorylation defect type 2?
Treatment for Combined oxidative phosphorylation defect type 2 (COXPD2) is largely supportive and symptomatic. Treatment may include dietary modifications, such as a low-fat diet, and supplementation with carnitine, coenzyme Q10, and riboflavin. Antioxidants, such as vitamin E, may also be recommended. In some cases, medications such as anticonvulsants may be prescribed to help manage seizures. Physical therapy and occupational therapy may also be recommended to help improve muscle strength and coordination. In severe cases, a heart transplant may be necessary.

Is there a cure/medications for Combined oxidative phosphorylation defect type 2?
At this time, there is no known cure for Combined Oxidative Phosphorylation Defect Type 2 (COXPD2). However, there are medications that can help manage the symptoms of the condition. These medications include anticonvulsants, anti-inflammatory drugs, and vitamins. Additionally, dietary modifications, such as avoiding foods high in fat and sugar, may help reduce symptoms.
