#227 Limb-Girdle Muscular Dystrophies with Louise Rodino-Klapac and Livija Medne
30:50 Share

In this episode, we are exploring limb-girdle muscular dystrophy (LGMD). Joining us for this conversation are two experts, Dr. Louise Rodino-Klapac, and genetic counselor Livija Medne.

Dr. Louise Rodino-Klapac) is the Executive Vice President, Head of R&D and Chief Scientific Officer at Sarepta Therapeutics) who has 15 years of experience researching and studying LGMD. She is renowned for her work in molecular genetics and gene therapy. Her pioneering research is the foundation for five of our investigational limb-girdle muscular dystrophy (LGMD) programs. Hear from Dr. Rodino-Klapac about LGMD, the importance of knowing your subtype and the basics of gene therapy!

Livija Medne) is a Senior Genetic Counselor and Systems Director of Genetic Counseling at the Children's Hospital of Philadelphia. She has 15+ years of experience in pediatric neuromuscular diagnoses, including LGMD. She co-chairs and is one of the course directors of the Curriculum Committee at the University of Pennsylvania Genetic Counseling Program. In addition, Livija is an advocate for the professional development of junior genetic counselors, having co-founded the first Genetic Counselor Mentorship committee at CHOP.

On This Episode We Discuss:

Limb-girdle muscular dystrophy (LGMD)

Which muscles are typically are affected first

Symptoms that individuals with LGMD experience and when symptoms usually start

The prevalence of LGMD compared to Duchenne Muscular Dystrophy

How people are diagnosed with LGMD

Why genetic testing is important to determine specific subtypes of LGMD

Gene therapy programs for the most common subtypes

The goal of the gene therapy

When FDA-approval for LGMD gene therapy can be expected

How patients can gain access to the gene therapy program and how health care providers can refer patients

Busting myths about LGMD

Which muscular dystrophy causes weakness of the muscles typically starting around the hips and shoulders? That would be limb girdle muscular dystrophy, or LGMD. LGMD is a group of neuromuscular diseases caused by mutations in genes responsible for proteins critical for muscle function, regulation, and repair1-3. Sarepta is a global biotechnology company working on engineering precision genetic medicine with the goal of changing the lives of people living with rare muscular dystrophies. Their multi-platform Precision Genetic Medicine Engine includes gene therapy, RNA and gene editing approaches. Oh that reminds me, ACMG is in March and Sarepta will be at booth 504.

Surely you have heard of whole genome sequencing, but what about rapid and ultra-rapid whole genome sequencing? This is an emerging method of diagnosing genetic conditions for quick management. PerkinElmer Genomics offers this incredibly valuable test, which can be life saving for ill babies and kids. Learn more in our full episode (**#226)) with PerkinElmer Genomics.

I’ve enjoyed recording a few episodes about epigenetics, one of the interviews where I learned the most was with the Diagnostic Labs at the Greenwood Genetic Center. They taught me about EpiSign which is a novel clinically validated test that analyzes methylation. I just learned that since this episode in 2021, verison 4 of EpiSign has been released which has expanded to include over 70 conditions. If you are attending ACMG this month stop by booth 607 to chat with Greenwood Genetics. In the meantime brush up on your epigenetics by listening to Episode #145 of DNA Today and visit *GreenwoodGeneticCenter)*. (Sponsored)
