Research and Updates

Information about the natural history and management of individuals with LDS continues to evolve.

Advances in medical and surgical care are continually being made to help decrease complications for those impacted by LDS. Initial studies reporting past medical histories of individuals with LDS revealed early ages for first cardiac surgery and for the average age of death. While these seem like frightening statistics, the cases presented in this study were representative of retrospective medical information.

In the recognition of a new syndrome, it is often the most severe cases that first come to medical attention. The first cases do not reflect the current rise in success in the treatment of individuals with LDS, including aggressive surgical intervention and comprehensive imaging. As more individuals are being diagnosed with LDS, we are seeing an incredible spectrum of clinical severity, and we are learning more about the natural history of LDS.

In families with more than one member having the same gene mutation responsible for LDS we see a variety of physical symptoms and vascular involvement. Although LDS is diagnosed most often in children, there has been a growing number of diagnoses in adults who are 50 and older.

Internationally, various institutions are developing methods to improve management and care of individuals diagnosed with LDS. As we increase awareness and education in the medical community regarding the physical findings associated with LDS, we hope diagnoses will be made earlier to continue to improve medical outcome.

It is expected that the outlook for individuals with LDS will continue to improve as more is learned about the disorder. We remain optimistic and enthusiastic about the development of effective therapies for Loeys-Dietz syndrome.

Because of the rarity and the newness of the disorder, there may be research opportunities available to help physicians and researchers learn more about the various complications. Continue to check the Research Recruitment page of our site for any available research updates.

Studies Seeking Participants

 
  • Dr. Pamela Guerrerio at the National Institutes of Health (NIH) is conducting a research study to learn more about Loeys-Dietz Syndrome and other related genetic syndromes, including Shprintzen-Goldberg syndrome.

    Evaluations may involve consultations with specialists (from Allergy, Immunology, Endocrine and Bone Health, Dentistry, Craniofacial Team, Occupational and Physical Therapy, Adult Gastroenterology, Audiology, ENT, and/or Pain and Alternative Medicine) and may include a blood draw, answering questionnaires, and radiology studies.

    Patients will not be charged for any service offered, and medical insurance is not required. The NIH will pay for travel and accommodations for any necessary follow-up evaluations. Interested patients should contact Ellen Zektser (zektsere2@niaid.nih.gov) to learn more about the study.

    Thank you for your consideration and support in trying to make further inroads into our understanding of Loeys-Dietz syndrome and related diseases.

  • Genetic counseling students at Sarah Lawrence College are interested in learning more about the experiences of individuals and partners of individuals with vascular connective tissue disorders (e.g., Marfan syndrome, Loeys-Dietz syndrome, Vascular Ehlers-Danlos syndrome, familial thoracic aortic aneurysm and dissection, etc.) and pursuing surrogacy via a gestational carrier or surrogate as an option for family planning.

    Who is eligible?

    Individuals or partners of individuals with a genetic or clinical diagnosis of a vascular connective tissue disorder (e.g., Marfan syndrome, Loeys-Dietz syndrome, Vascular Ehlers-Danlos syndrome, familial thoracic aortic aneurysm and dissection, etc.) who were counseled on pursuing surrogacy or pursued surrogacy via a gestational carrier or surrogate as part of family planning.

    What is involved?

    One 60-minute virtual semi-structured interview per participant with approximately ten planned questions and time for additional follow-up questions as needed.

    Study participants will receive either a $50 VISA gift card or the option to donate this amount to an organization of their choice.

    For more information or to participate, email SLCAATHESIS@GMAIL.COM.

  • Are you interested in helping researchers develop the world’s largest database for children and young adults with genetic aortic disease? Researchers at Texas Children’s Hospital are interested in learning more about young people with aortic disease that has a genetic basis. They are asking for your help because there are currently no medical guidelines on how to best manage aortic dilation in children, and little is known about the long-term outcomes of these genetic conditions.

    In an effort to learn more, researchers will collect clinical information from your medical records to better understand how the aorta changes over time, and how your genotype (your unique genetic code) affects your disease. This information will help create guidelines that will provide better tools for doctors to diagnose, estimate risks, and treat children and young adults with genetic aortic disease. These guidelines aim to improve the care and quality of life for individuals diagnosed with these conditions.

    One is eligible to participate in the CLARITY study if they were diagnosed under age 50 and meet one of the following criteria:

    1. Classic Marfan syndrome with either FBN1 mutation or history of lens dislocation/subluxation

    2. Early-onset/ Neonatal/ Infantile Marfan syndrome with FBN1 mutation

    3. Loeys-Dietz syndrome with TGFBR1, TGFBR2, TGFB2, TGFB3, SMAD2, or SMAD3 mutation

    4. Vascular Ehlers-Danlos syndrome with COL3A1 mutation

    5. Arterial Tortuosity syndrome with SLC2A10 mutation

    6. Shprintzen-Goldberg syndrome with SKI mutation

    7. Cutis Laxa Type 2B with recessive EFEMP2/FBLN4 mutations

    8. ACTA2-associated aortic or arterial disease

    9. FLNA-associated aortic or arterial disease

    10. LOX-associated aortic or arterial disease

    11. MYLK-associated aortic disease

    12. MYH11-associated aortic disease

    To participate, you will be asked to sign a consent form and a medical records release form to allow the research team to collect personal medical information related to your genetic diagnosis. This information will be stored in a secure database and used for study analysis. Other than signing these forms, research participants will not be asked to take any further actions, such as attending research visits, participating in clinical trials, etc.

  • Researchers at Stanford University are interested in learning how the use of resources (e.g., meetings, community events, social media, etc.) changed before and during the COVID-19 pandemic as well as how patients want to access resources moving forward. The study team will use the insight they gain to help healthcare providers, organizations, and support groups better tailor resources for the communities they serve.

    In this study, participants will be asked to complete an anonymous online survey. The survey is estimated to take approximately 15 minutes or less and will ask questions regarding resources used prior to the COVID-19 pandemic, during the COVID-19 pandemic, and perceived benefits and drawbacks of these resources. The survey also contains questions that investigate preferences for resource use moving forward.

    Individuals must meet the following criteria to participate in the study:

    • Be 18 years or older

    • Have, or have a child with, one of the following conditions:

      • Vascular Ehlers-Danlos syndrome

      • Marfan syndrome

      • Loeys-Dietz syndrome

      • Hereditary thoracic aortic disease

    To complete the anonymous survey, go to https://StanfordUniversity.Qualtrics.com/JFE/FORM/SV_BE4TYJMOSVLABKS.

  • The NIGMS (National Institute of General Medical Sciences) Repository, housed at the Coriell Institute, is a research biobank that collects blood and/or tissue samples from individuals with genetic diseases and makes them into cell lines and DNA for scientists to use in biomedical research. Loeys-Dietz syndrome (LDS), Vascular Ehlers-Danlos syndrome (VEDS), and Marfan syndrome were recently listed on the American College of Medical Genetics and Genomics list of actionable conditions for increased research.

    Coriell is now accepting blood (for lymphoblasts) and skin biopsy (for fibroblasts) samples from individuals with LDS, VEDS, and Marfan syndrome as well as their family members and relatives from domestic and international locations around the world.

    Donors will receive a sample collection kit, instructions, and all necessary materials for collecting samples and returning the kit free of charge. Sample donors are required to submit supporting clinical data (e.g., genetic test results, medical records, physician summary records) that describes the diagnosis.

    To submit a sample to the NIGMS Repository, email NIGMS@CORIELL.ORG with the following information:

    The requested number of blood and skin biopsy collection kits for your family member(s)

    Full name and age (for children) of each family member who will donate samples

    The name, address, and phone number of the person or clinician to whom the collection kit(s) should be shipped.

    Coriell does not conduct its own research but provides the materials for scientists around the world to perform research on genetic disorders. Also, Coriell does not provide donors with any results regarding their genetic disease nor information on their sample itself.
