Tests & Diagnosis

Newline Maker

Is genetic testing available for fragile X syndrome?

Yes, genetic testing is available for fragile X syndrome. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk are possible if the diagnosis of an FMR1-related disorder (including fragile X syndrome) has been confirmed in a family member.[1]

The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for fragile X syndrome. The intended audience for the GTR is health care providers and researchers. People with questions about genetic testing should speak with a health care provider or genetics professional.

Testing

  • The American College of Medical Genetics (ACMG) Laboratory Quality Assurance (Lab QA) Committee has the mission of maintaining high technical standards for the performance and interpretation of genetic tests.  In part, this is accomplished by the publication of the document "ACMG Standards and Guidelines for Clinical Genetics Laboratories." These standards and guidelines are designed primarily as an educational resource for clinical laboratory geneticists to help them provide quality clinical laboratory genetic services.
