IThey live with a Damocles sword above their heads. “Since he was very young, Eden has suffered from digestive disorders. But, despite examinations and visits to several specialists, we were assured that he was fine,” recalls Tomy, the father of the family. Farah was always convinced that something was wrong. In October 2020, the family welcomes another little boy, Abel. Eden, he was hospitalized in March 2021 when he was four years old. The medical team once once more carried out numerous examinations and various analyses.
Thanks to the results of a blood test, urine tests and genetics, the medical team finds that the dosage of heparan sulphate in Eden’s urine is not normal. “We received a letter informing us of this result and explaining to us that it might be a sign of certain diseases, including Sanfilippo syndrome”, explains the young thirty-year-old. Quickly, a test confirmed the presence of the same disease in the five-month-old child.

Alzheimer infantile
Sanfilippo syndrome results from an accumulation of heparan sulphate molecules. “This is due to a genetic mutation which affects the activity of an enzyme necessary for the breakdown of heparan sulphate. These badly degraded molecules, which cannot be eliminated, hinder the normal development of the brain and then destroy the brain cells”, indicates the Institut Pasteur, which recalls that the first symptoms are a delay in cognitive development associated with hyperactivity, behavior autism and sleep disorders. Generally, the first signs of the disease appear before the age of three. “You need two parents carrying the mutation and their children have a 25% risk of being sick, and a 50% risk of carrying a mutated gene, without being sick”, details the Alzheimer Research Foundation.
This syndrome, also called infantile Alzheimer’s, affects around 150 children in France. About 15 have type C, like Abel and Eden. “Our sons are growing normally, the disease does not necessarily manifest itself. But, they will reach a plateau and then start to degrade. Over the years, they will lose what they have learned,” explains Tomy. Around the age of ten, the neurological impairment leads to an intellectual disability and a reduction in motor skills which lead to a loss of autonomy. Today, this disease is incurable. It is only possible to relieve certain symptoms.

“We are fighting a crazy fight to save the lives of our children. Currently, there is a lack of funds to set up a clinical trial. For this, we have opened an online kitty, ”explains the father of the family. In this race once morest time, nearly 980,000 euros have already been collected. 500,000 euros are needed to finance a so-called “Natural History” clinical study of Sanfilippo disease in France. This is a mandatory prerequisite before conducting the clinical trial. During this first step, there is no medicinal aspect.
Since this first ordeal, the family has grown and the two boys now have a little sister. For her, a screening was carried out before birth and she is not a carrier of the disease. “This double announcement of the incurable disease of our sons was the worst moment of our lives. Nothing will ever be the same once more, it’s a shift towards the unknown. Our therapy for us is this fight. It is thanks to this that we have recovered. Today, despite the horror of what is happening to us, we have decided to live each moment intensely and always bring joy to our homes. The second stage of this clinical trial will be gene therapy aimed at injecting the missing functional enzyme into the brain. Only option to modify the evolution of this disease.
