• Raising Awareness and Research Funds for  

    IRF2BPL Disorder

    This website provides the information on IRF2BPL-related disorders for patients, family members, physicians and biomedical scientists working all together to solve the medical mystery on IRF2BPL.  

    See Marcogliese et al., 2018 American Journal of Human Genetics  for details.

    Leo's Story

Children with a mutation on IRF2BPL gene are born healthy.  But as early as 6 months old, they begin to display progressive, severe neurodevelopmental regression.  They commonly suffer from loss of ability to control their muscles and often develop seizure.   Some children also develop various levels of Autism Spectrum Disorder (ASD).  In most severe cases, the children become unable to walk, stand, sit, speak, and swallow, and  bound to a wheelchair, feeding tube, and oxygen tank.    

Almost nothing is known about the gene and no treatment exists for the disease.  

But in summer 2018, an international group of researchers has discovered that IRF2BPL mutations lead to neurodegeneration in fruit flies, which gives patients and family members a hope for a possible cure in the future.  

IRF2BPL Foundation, together with Stand By Eli Foundation, is dedicated to raise awareness and research funds to save children with IRF2BPL disorders.


Clinical database protocol for IRF2BPL patients now approved at Cincinnati Children's Hospital! 

Dr.  Loren DM Pena, MD, PhDClinical Geneticist and Associate Professor at Cincinnati Children's Hospital, has made a big step toward  understanding the disorder caused by IRF2BPL gene mutations!

Dr. Pena specializes in natural history study and her 
clinical database protocol plan for IRF2BPL patients has been approved by Cincinnati Children's Hospital!   IRF2BPL Support Group welcomes the approval and sincerely thanks Dr. Pena for her dedication and contribution toward the ultimate cure for the disease!  

Please refer to the protocol summary below.  All IRF2BPL  patients and family members are strongly encouraged to participate in the protocol. IRF2BPL Support Group will share the details with the group members soon, but please contact Dr. Pena directly at when you have questions. 
Again, a big thanks to Dr. Pena and Cincinnati Children's Hospital!  We will find cure for the disease together!

Title:  Database of clinical data for individuals with variants in the IRF2BPL gene

CCHMC IRB 2018-6357

We are interested in learning more about the findings and symptoms of individuals with changes in the IRF2BPL gene. This condition is also known as Neurodevelopmental Disorder with Regression, Abnormal Movements, Loss of Speech and Seizures (NEDAMSS). We have created a database to collect health care information on individuals affected with this condition. There are no additional visits, blood draws, or other investigations that are required to participate in this study.  We are hoping that, by collecting this information, we will be able to understand the symptoms and complications associated with the condition, and to utilize this information to best care for individuals with this condition.  If you would like to receive additional information, please contact Dr. Loren Pena at
