Duchenne Muscular Dystrophy: Causes, Symptoms & Treatment

Duchenne Muscular Dystrophy (DMD) is one of the most severe forms of muscular dystrophy, primarily affecting boys between the ages of 2 and 5. It is caused by a mutation in the dystrophin gene, leading to progressive muscle degeneration and weakness.

In India, managing DMD requires long-term medical care, physiotherapy, medications, cardiac monitoring, and sometimes ventilatory support. Due to the lifelong nature of treatment, many families explore medical crowdfunding as a financial support option. Increasingly, medical crowdfunding platforms are helping parents manage therapy costs and ongoing care expenses.

The human body is an amazing mechanism. For centuries, humans have tried to learn more about how it works. Yet, despite our efforts, there are times when some parts of the body don’t function as they should- the body’s muscles or tissues do not grow or work properly, instead, they die. One such genetic disorder is Duchenne Muscular Dystrophy (DMD).

What is Duchenne Muscular Dystrophy (DMD)?

Duchenne muscular dystrophy (DMD) is a genetic disorder that causes progressive muscle weakness and degeneration. Out of over 30 types of muscular dystrophy, DMD accounts for about half of all cases. Named after the French neurologist Guillaume-Benjamin Duchenne, who first described it in 1861, DMD primarily affects boys due to the inheritance of deleted exons from the birth mother’s X chromosome.

• A woman carrying the defective DMD gene has a 50% chance of passing it on to her children.
• DMD affects 1 in every 3,500-5,000 male births worldwide.

What Causes Duchenne Muscular Dystrophy?

Duchenne muscular dystrophy is caused by a mutation in the DMD gene, which is responsible for producing dystrophin. Dystrophin is like a shock absorber. It helps the muscles handle everyday wear and tear of muscles from activities like walking, running, or even breathing.

What Makes Dystrophin So Important

Dystrophin is a key component of the dystrophin-glycoprotein complex (DGC), a group of proteins that connect the cytoskeleton (internal muscle cell structure) to the extracellular matrix (outside the cell).
This connection anchors the muscle fibres and helps stabilize the muscle cell membrane during contraction and relaxation.

Prevents Muscle Cell Damage

During muscle movement (contraction/relaxation), immense force is generated, which can stress the cell membrane.
Dystrophin acts as a shock absorber, protecting muscle fibres by distributing mechanical stress across the cell membrane.
Without dystrophin, the membrane becomes fragile, leading to tears, leakage, and eventual cell death.

Maintains Calcium Balance    

Dystrophin helps maintain the integrity of the muscle fibre membrane, preventing unwanted calcium ions from leaking into the cell.
Excess calcium can activate enzymes that break down proteins and further damage the muscle cells. Dystrophin facilitates the transmission of force generated inside the cell to the surrounding tissue.
Proper force transmission is essential for coordinated muscle movement and strength.

Dystrophin helps preserve muscle cell function by

• Preventing the accumulation of cellular damage.
• Supporting healthy muscle regeneration after physical activity.

Without dystrophin, muscle fibres undergo progressive degeneration, as seen in conditions like Duchenne Muscular Dystrophy (DMD).

When dystrophin is missing or defective (due to genetic mutations), muscle cells experience:

• Damage in fragile membranes
• Protein degradation caused by calcium imbalance
• Reduced structural stability and force transmission.
• Progressive muscle degeneration and weakness.

This is why dystrophin is crucial for muscle health, and its absence leads to severe conditions like Duchenne Muscular Dystrophy.

So, when the DMD gene is mutated:

• The body makes little or no dystrophin.
• Muscles become fragile.
• Over time, muscle cells break down and die, leading to a loss of muscle function.

Symptoms of DMD

Duchenne Muscular Dystrophy (DMD) symptoms usually appear between ages 2-5 and worsen over time. Common signs include:

• Decreased heart function
• Cardiomyopathy
• Heart failure
• Weak diaphragm
• Respiratory failure
• Loss of muscle mass
• Inflammation
• Fibrosis
• Requires wheelchair

Eventually, DMD can affect vital functions like heart and lung activity, often requiring medical interventions. Over time, the heart function decreases, leading to cardiomyopathy and potential heart failure.
Additionally, weakened respiratory muscles, like the diaphragm, result in breathing difficulties, often progressing to respiratory failure. Inflammation and fibrosis in the muscles further deteriorate mobility, eventually requiring affected individuals to rely on wheelchairs for movement.

Duchenne Muscular Dystrophy Treatment Options

Finding a cure for Duchenne Muscular Dystrophy is challenging, but advancements in medical science offer hope through therapies that slow disease progression and improve life expectancy.

Gene Therapy: Elevidys

One of the most promising breakthroughs is Elevidys, a gene therapy approved by the FDA. It introduces a modified version of the dystrophin gene to produce a functional protein, aiming to stabilise and preserve muscle function.

• FDA Approval: In June 2024, Elevidys was approved for all patients with DMD aged 4 and older, regardless of whether they can walk or not.
• Elevidys Cost and availability: The therapy is expensive, with a one-time administration costing approximately $3.2 million (around ₹29 crore). This makes affordability a significant challenge, especially in countries like India.

Exon-Skipping Therapy

Exon skipping works like putting a “patch” over the broken part of the gene to help it function better.

• How it works: Scientists use antisense oligonucleotides (AOs) to skip over the faulty exon. This helps the body produce a shorter but functional version of dystrophin.
• Example: If a person has an exon 22-41 deletion, exon-skipping therapy targets exon 42 to restore the connection and help the body produce dystrophin.

While therapies like Elevidys and exon skipping address the genetic cause and improve life expectancy, physiotherapy for DMD patients helps maintain muscle strength and flexibility. It also reduces the risk of joint contractures and improves quality of life.
