3-Methylcrotonyl-CoA Carboxylase Deficiency Risk Calculator
3-Methylcrotonyl-CoA Carboxylase (3-MCC) deficiency is a metabolic disorder impacting the catabolism of the amino acid leucine. This condition is one of the most common metabolic disorders and can result in the accumulation of harmful intermediates due to the body’s inability to properly break down leucine.
What is 3-MCC Deficiency?
3-MCC deficiency occurs when there are mutations in the MCCC1 or MCCC2 genes, which encode the enzymes necessary for the breakdown of leucine. Individuals with this deficiency may exhibit a variety of symptoms, including feeding difficulties, lethargy, and poor muscle tone. The condition is inherited in an autosomal recessive manner, meaning both copies of the gene in each cell have mutations.
Risk Factors
Several factors can increase the risk of having or passing on 3-MCC deficiency:
- Family History: Individuals with a family history of 3-MCC deficiency are at higher risk.
- Genetic Mutations: Mutations in the MCCC1 and MCCC2 genes are direct indicators.
- Symptoms in Early Life: Symptoms such as feeding difficulties and hypotonia in infants may indicate the presence of this disorder.

How to Use the 3-MCC Deficiency Risk Calculator
A risk calculator for 3-MCC deficiency can help individuals understand their potential risk level based on specific criteria. Here’s a simplified way to evaluate your risk:
- Input Age: Younger children, especially infants, are typically evaluated more frequently.
- Gender: While 3-MCC deficiency can affect any gender, documenting this information helps in personalizing health care advice.
- Family History: Indicate if there’s a known family history of 3-MCC deficiency.
- Symptoms: Check for symptoms such as feeding difficulties or muscle weakness.
Example Risk Calculation
Suppose a parent is concerned about their infant. By entering the child’s age, noting any symptoms, and considering family history, the calculator can provide an estimate of risk level. While a simple online tool can give an indication, genetic testing and consultation with a healthcare provider are essential for accurate diagnosis and management.
3-MCC deficiency is a serious metabolic disorder, but understanding your risk can lead to early diagnosis and better management. Using tools like a risk calculator can be a first step in identifying the need for further medical evaluation.
