Rare Disease Research at Moderna

About mRNA

in Rare Diseases

Moderna is committed to researching and developing mRNA therapies for patients living with rare diseases. There are approximately 7,000 rare diseases that affect more than 300 million people worldwide.1 Yet there are approved drugs for only 5 percent of rare diseases.2 We understand the urgency with which patients and caregivers are waiting for potentially novel therapeutic options, so we are working tirelessly to research potential mRNA treatments.

mRNA is a messenger molecule that carries instructions for making proteins to cells. This science could be applied to diseases where the body does not properly make protein, like many rare diseases.

Moderna’s Rare Disease Research

Propionic Acidemia (PA)

Methylmalonic Acidemia (MMA)

Propionic Acidemia (PA)

People who are diagnosed with propionic acidemia (PA) are missing the propionyl-CoA carboxylase (PCC) enzyme, which is responsible for the breakdown of certain proteins and fat. When this enzyme is missing, it is difficult for cells in the body to turn food into energy, leading to toxins building up in the bloodstream.

Methylmalonic Acidemia (MMA)

Methylmalonic acidemia, or MMA, is a rare organic acid disorder causing metabolic crises, seizures, developmental delays, and more. The most common form of MMA is caused by changes in the gene called the MUT gene. This gene provides instructions for making the MUT enzyme, which is responsible for the proper breakdown of certain proteins and fats. When this enzyme is missing, it is difficult for cells in the body to turn food into energy, leading to toxins building up in the bloodstream.
