What is MEF2C Related Syndrome?

MEF2C Related Syndrome is a rare disease which causes profound disabilities. You can help us to improve the quality of life of our children.

What causes MEF2C Related Syndrome?

MEF2C Related Syndrome presents itself when there are pathogenic changes to the MEF2C gene. These changes can prevent the gene from working as it should.

We are finding that there are many different types of MEF2C mutations out there. It is our goal to fund research and development that will lead to treatments and a cure for all MEF2C mutations. 

How rare is this diagnosis?

At this time we have a population of approximately 400 patients globally, with nearly half of our patients in the United States. We strongly suspect that there are many more patients out there, not yet diagnosed. If patients do not have seizures, they are often diagnosed with autism and many are not advised to have genetic tests performed to determine if there is an underlying genetic condition causing these symptoms.

A natural history study will assist in the examination of the different types of mutations within our patient group and to understand how this will affect treatment options.

What are the symptoms?

MEF2C Related Syndrome presents a broad range of symptoms including:

  • Global Developmental Delay

  • Severely Impaired or Absent Language

  • Profound Learning Difficulties

  • Epilepsy (seizures)

  • Severe Hypotonia / can be mixed with hypertonia

  • Stereotypical & Repetitive Movements

  • Sleeping Difficulties

  • Feeding Difficulties

MEF2C Related Syndrome is considered a severe form of Autism Spectrum Disorder (ASD).

Is there a treatment?

There are no MEF2C targeted therapeutics currently available; and therefore we must invest in extensive research and development to find treatments and a cure.
