Your Question

I have MTHFR deficiency and I have four children; I am interested in having them genetically tested for the condition. I would also be interested in taking part in a study if there is anyone conducting research on this condition. Additionally, I am always looking for updated research from medical journals. Where can I go for the most current and reliable research articles on MTHFR?

Our Answer

We have identified the following information that we hope you find helpful. If you still have questions, please contact us.

Is genetic testing available for homocysteinemia due to MTHFR deficiency?

Genetic testing for homocysteinemia due to MTHFR deficiency is available. It should be noted that health problems tend not to be related to whether someone has a MTHFR gene mutation or even a MTHFR enzyme deficiency, but whether the deficiency is leading to elevated levels of homocysteine in the blood (homocysteinemia) or urine. GeneTests lists the names of laboratories that are performing clinical genetic testing for MTHFR deficiency. To view the contact information for the clinical laboratories conducting testing click here.

Please note: Most of the laboratories listed through GeneTests do not accept direct contact from patients and their families; therefore, if you are interested in learning more, you will need to work with a health care provider or a genetics professional.

How can I find a genetics professional in my area?

Genetics clinics are a source of information for individuals and families regarding genetic conditions, treatment, inheritance, and genetic risks to other family members. More information about genetic consultations is available from Genetics Home Reference. To find a genetics clinic, we recommend that you contact your primary healthcare provider for a referral.

Where can I find out about participating in clinical trials or current research being conducted with individuals who have homocysteinemia due to MTHFR deficiency?

The U.S. National Institutes of Health, through the National Library of Medicine, developed to provide patients, family members, and members of the public with current information on clinical research studies. This Web site lists clinical trials that are either currently enrolling individuals with MTHFR deficiency, active but not recruiting individuals with the condition, or completed. To find these trials, click on the link above and use "homocysteinemia due to MTHFR" as your search term. After you click on a study, review its "eligibility" criteria to determine its appropriateness. Use the study’s contact information to learn more. Check this site often for regular updates.

You can also contact the Patient Recruitment and Public Liaison (PRPL) Office at the National Institutes of Health (NIH)to speak with a specialist, who can help you determine if you are eligible for any clinical trials. If you are located outside the United States, and would like to be contacted via telephone, you will need to provide your telephone number in full, including area code and international dialing prefix.
