The Sweet Medical Career of Dr Eva Morava!

Congenital Disorders of Glycosylation (CDG)— a rare sugar disease with 1000 sweet faces known worldwide!


My name is Vanessa Ferreira, a volunteer at the Portuguese Association for CDG (APCDG, www.apcdg.com). I am delighted to interview  Dr Eva Morava, who played an extraordinary role in uncovering the importance of sugars trees in 2 of the most important molecules for the human body, named proteins and lipids. She is one of the most interesting people in medicine. Welcome—it's wonderful to have you with us at CDG One-to-One!

Vanessa Ferreira: You have been working on CDG for more than 2 decades. What made you move into the field of such a rare and serious disease?

Dr Morava: I was a fellow in medical genetics 20 years ago when I read the paper wrote by Prof. Jaeken on this new, rare disease. I gave a summary to my colleagues on the unique features and I never forgot about this first genetics lecture I gave. I actually diagnosed the first patient 4 years later, when returned back from my US training to Hungary.  You would laugh me out, that I am this sentimental person, probably, but my patient had such a sweet face, and even though she was very sick, and weak, but she was always laughing. I never followed patients with any handicap before with such a happy nature. It’s hard not to fall in love with patients with CDG.

What are the biggest lessons out of those 2 decades of basic and applied research on CDG for you?

We have been searching for new disorders and trying to understand the pathomechanism, but we were unable to come up with sufficient options and ideas for therapy. Being a clinical biochemical geneticist, I chose a profession to treat patients with different diets, cofactors and even with enzyme treatments, but we do not have a good therapy for most of CDGs. Our focus has to move from diagnostics to treatment, and clinical research has to get support from the academic world and from legislators as well.  

A victim of limit budget on rare diseases?

CDG were first reported in the medical literature in 1980 by Dr. Jaak Jaeken and colleagues. Thirty six years after, most forms of CDG, still do not have a therapy.

You are driving basic and applied research for CDG and related rare diseases. Why do we still not have a cure for the most common form of CDG, namely PMM2-CDG?

We could offer a cure for most of the symptoms of PMM2-CDG by enzyme replacement, or chaperone therapy or genetic manipulations. The real important question is though, what can we do for the central nervous system disease. Patient already have a brain malformation in most cases of PMM2-CDG at birth; can we treat that, or could we prevent that, to be able to “treat the brain” as well, and not only “the body” in CDG? Currently, we do not have a treatment option to “reset” organs, which had a developmental problem during fetal life. Theoretically, to do that, we would need to know the diagnosis very early and would need to treat the patients before they are born. This is still utopistic in 2016.

Let's say that you can dream and you have a really big idea to find a cure for PMM2-CDG. What would be your 2 priority actions to achieve this goal?

 Such a wonderful cure should be evaluated for safety as soon as possible in animal models that we could set up clinical trials to evaluate patient response. This is a question of communication, management, logistics, financial support, collaboration; many of these already exist in our worldwide CDG network. Awareness, legislation   and finances, these are always chronic problems in Orphan disorders…

Long-term impact of the current research

There are relevant initiatives around the globe for CDG. For example, there is a large initiative in the USA called “Clinical and Basic Investigations into Known and Suspected Congenital Disorders of Glycosylation” and also the RareCommons Spanish project. Is there a sense that maybe over time there would be more similar initiatives or a merge among these initiatives through international cooperation? What would be the 2 main advantages for CDG research?

I think these networks are essential to solve the most important scientific questions around CDG. May be we do not need more initiatives, only sharing data (trusting each other with new findings and sharing ideas) and good communication between groups. Actually, I do see this communication growing rapidly.

CDG are one of the most rapidly growing family of monogenic diseases. Currently, more than 100 different forms of CDG have been identified. How do you feel that this momentum will help shaping future therapies?

This could help with awareness, but it is difficult for therapy initiatives, because there is not much unifying factor known in these disorders helping therapeutic ideas. However the growing numbers increase awareness, and that brings more scientists involved in the field.   

What role do CDG patient advocacy groups have to boost CDG knowledge and future therapies?

The patient advocacy groups are the most important to push our legislators towards decisions to support research, especially research on therapy in rare disorders. We, clinicians and scientists have almost no impact on these issues compared to the support groups, to be honest. I am very happy that the CDG group is getting stronger and stronger.  
Some doctors that are starting to work on CDG are isolated in what concerns CDG expertise or diagnostic tools. What do you have to tell to them?

I think the scientific community and the clinician network is strong and open in embrace anybody who wants to join us.        

CDG families love your optimism, remarkable ability to communicate and special charisma. What message do you have for them?

It is an honor to have parents trust. Their children are unique, sweet, smart, wonderful, who would not be happy to be involved and try to make a difference?   I hope I can continue to be a physician and especially a physician working with children. Children are born with optimism. They never give up. I just follow their lead.   

Work and personal live

You have a brilliant professional career divided between USA, Belgium and Hungary. In addition, you are mother, wife, daughter and you have lots of friends and followers on Facebook! Can you tell us the secret to combine everything at once?

I think that the secret that I love what I do, and I feel loved by the others, and that gives enough positive energy to go.

About Eva Morava

Morava revolutionized CDG basic and clinical research. She is Professor of Pediatrics at Tulane University Medical Center, New Orleans, Louisiana (USA) and metabolic pediatrician at the UZ Leuven, Belgium. Recently, she became the Editor in Chief at the Journal of Inherited Metabolic Disease at the Society for the Study of Inborn Errors of Metabolism (SSIEM). Morava pioneered the development of new diagnostic tools, algorithms and therapies for CDG. She published 216 articles. Morava is a member of the national and international committees and scientific advice groups. She has strong collaborations with patient groups with whom she conducts patient-oriented resources and research. Pf Morava is a remarkable inspiration. Her opinions help to make a difference in the lives of CDG children and adults.
