Sarcosinemia: Causes, Signs, and Treatment
Sarcosinemia is a rare inherited disorder that affects how the body breaks down a specific amino acid called sarcosine. This condition can lead to an accumulation of sarcosine in the blood and other body tissues. The primary impact of sarcosinemia on health is related to the disruption of normal metabolic processes, which may have implications for overall well-being and bodily functions.
Symptoms of Sarcosinemia
Sarcosinemia is a genetic disorder with symptoms that affect various aspects of an individual's health.
- Developmental delays
- Intellectual disability
- Speech difficulties
- Low muscle tone
- Movement disorders
- Seizures

Get Second OpinionCauses of Sarcosinemia
Sarcosinemia is primarily caused by a genetic mutation that leads to the body being unable to break down sarcosine properly.
- Genetic mutations
- Deficiency of enzymes involved in sarcosine metabolism
Types of Sarcosinemia
Sarcosinemia can present in various forms, each with distinct characteristics and manifestations.
- Sarcosinemia Type I: A rare genetic disorder characterized by the body's inability to break down the amino acid sarcosine properly.
- Sarcosinemia Type II: Another form of the condition which is caused by a deficiency in the enzyme sarcosine dehydrogenase.
- Sarcosinemia Type III: A subtype of the disorder associated with mutations in the SARDH gene, leading to impaired sarcosine metabolism.
- Sarcosinemia Type IV: This type is linked to mutations in the DMGDH gene, affecting the enzyme dimethylglycine dehydrogenase involved in sarcosine breakdown.
- Sarcosinemia Type V: A variant of the disorder resulting from mutations in the GLYCTK gene, impacting the enzyme glycine Cacetyltransferase and disrupting sarcosine metabolism.
Risk Factors
Sarcosinemia risk factors include a family history of the condition or consanguinity, with symptoms usually appearing in infancy or childhood.
- Inherited genetic mutations
- Family history of Sarcosinemia
- Consanguineous marriages
- Ethnicity (more common in certain populations)
- Advanced maternal age during pregnancy

Diagnosis of Sarcosinemia
Sarcosinemia is typically diagnosed through specific tests that evaluate the levels of certain substances in the blood or urine.
- Newborn screening
- Genetic testing
- Urine amino acid analysis
- Blood tests
- Enzyme assays
Treatment for Sarcosinemia
Sarcosinemia is typically managed through dietary adjustments and close monitoring by healthcare providers.
- Dietary restriction of certain amino acids: Limiting the intake of certain amino acids, especially glycine and serine, can help manage symptoms of Sarcosinemia by reducing the buildup of toxic metabolites.
- Supplementation with vitamin B6: Supplementing with vitamin B6 can aid in the breakdown of excess sarcosine, which may help alleviate symptoms of Sarcosinemia.
- Medications to manage symptoms: Certain medications may be prescribed to help alleviate specific symptoms associated with Sarcosinemia, such as seizures or developmental delays.
- Regular monitoring and followup: Regular monitoring of blood amino acid levels and overall health status is essential in managing Sarcosinemia to ensure timely adjustments to treatment plans.
- Genetic counseling: Genetic counseling can provide valuable information about the inheritance pattern of Sarcosinemia and help individuals and families make informed decisions about family planning and genetic testing.

040-68334455Frequently Asked Questions
What is Sarcosinemia?
Sarcosinemia is a rare inherited metabolic disorder characterized by the body's inability to break down and utilize the amino acid sarcosine properly.
What are the symptoms of Sarcosinemia?
Symptoms of Sarcosinemia may include developmental delays, intellectual disability, speech difficulties, and behavioral issues.
How is Sarcosinemia diagnosed?
Sarcosinemia can be diagnosed through genetic testing, urine tests to measure elevated sarcosine levels, and clinical evaluation of symptoms.
Is there a treatment for Sarcosinemia?
There is no specific treatment for Sarcosinemia. Management involves symptom-based care and dietary modifications to minimize intake of certain amino acids.
Can Sarcosinemia be prevented?
Since Sarcosinemia is an inherited disorder, it cannot be prevented. Genetic counseling may be recommended for individuals with a family history of the condition.
