5p- Syndrome Resources for Newly Diagnosed Families
Most likely, the first time you heard the term Cri du Chat or 5p- syndrome was the day someone you love received the diagnosis. At Cri du Chat Research Foundation, we try to take some of the fear out of the diagnosis by providing information not only for new families but also for all families as their children continue to grow older. If you don’t find answers to your questions, please email info@criduchatresearch.org anytime. You are not alone – 5p- syndrome is a community of families just like you, devoted to helping.
Individual documents may be printed through links within this document. Here is a to all printable materials listed below.
First Steps…
What is 5p- syndrome ? (link to the page on website covering this information) It is important for you to know your child’s genotype (where their deletion breakpoint is, do they have duplications etc?). Knowledge is power.
Provide your doctors with the ICD-10 Code (provide link to this info on website) & this medical consideration document (provide link once document is complete)
Connect with CDCRF (link to google doc ("register with CDCRF to receive the latest news, keep the 5p- syndrome Census up to date, and learn about potential studies and clinical trials. a support network of others with similar experiences will help make your life easier”)
Join 5p- syndrome registries (link to the page on website covering this information)
Print and/or save this checklist (provide link to document once complete) for these & other priorities

Every family can share their data for research
The single most important thing that families can do to help this community is to sign up for the Citizen Health Natural History Study at (provide link here)
Citizen Health (formerly Ciitizen) is the largest single study of 5p- patients
Close to 100 families in the US have already signed up making this the largest single study of 5p- syndrome patients in the world.

We need to find a 5p- syndrome biomarker. Finding a biomarker is under our “clinical trial readiness” pillar.
CDCRF is hopeful — based on a number of biopharma companies we are in touch with — that there will be 5p- syndrome clinical trials in the near future. Finding a biomarker will help prepare for these trials now once a trial is ready to go. To be best prepared, it would be very helpful, if not necessary, to have a way to measure how a drug or therapy being tested affects the level of proteins in the patients. A 5p- syndrome biomarker associated with critical pathways for major contributor genes will help solve this problem. If we can identify a biomarker now, we will be ready to go as soon as a drug is ready to be tested.
Currently, there is one biomarker that exists for 5p- syndrome for a specific pathway. However, without biomarkers associated with critical genes it will be difficult to show to the FDA, during a trial, that a drug is working for 5p- syndrome patients.
What is a biomarker?
A biomarker helps determine if a drug works.
In general terms, a biomarker is an observation/measurement that can help researchers determine if a treatment is working for a particular disease. More specifically, a biomarker is a medical way to measure the progress of a disease or the effects of a treatment. So, instead of relying on patient or parent reports, observing changes in symptoms, etc., a biomarker is a more scientific and reliable way to determine whether or not a treatment works.
Overall, the predetermined biomarker measurement for a disease is compared with the measurements during treatment in order to observe any changes that result from the treatment.
What’s an example of a well-known biomarker?
Cholesterol & HbA1C
A well-known example of a biomarker is cholesterol for heart disease. High cholesterol has been found to be associated with high risk for heart disease. Therefore, if a trial drug for lowering risk of heart disease results in lowered cholesterol, we know that the drug is likely working.
A second example of a well-known biomarker is A1C levels for patients with diabetes. The A1C level of a patient serves as a biomarker for diabetes, and that predetermined level is compared with the levels during a trial drug treatment to see if the drug is working.
Why are we working to develop an EEG data to create a 5p- syndrome biomarker?
It makes sense.
As all 5p- syndrome families know, Epilepsy patients undergo EEGs to monitor abnormal brain activity. The hypothesis among 5p- syndrome researchers and other researchers working on NDD (neuro developmental disabilities) is that 5p- syndrome may have a unique pattern in these EEGs which could serve as a biomarker.
Since many patients with 5p- syndrome have had an EEG, the results if show a consistent pattern would be useful in trials for those individuals? If a drug changes that unique pattern (that we haven’t found yet) during clinical trials, then we could argue that the therapy works.
Families should submit your child's EEG (Not the report but the actual tracing) to Matrix. This will allow us to develop a biomarker using these EEG results. Biomarkers are essential for clinical trial design. We need your participation! Register for Matrix and submit your child's EEG tracing (from any point in their life) for our 5p- Syndrome EEG bank.

So why are we collecting biofluids (blood and saliva) too?
To cover our bases & save donors money.
We are hopeful that there will be an EEG biomarker, but it’s worth taking a closer look at blood and saliva as well. A number of researchers have asked for this.
Since we will already have patients in world-class medical centers, we want to collect samples in a consistent way and make them available to researchers who are looking at biofluides as biomarkers. This is the most cost-effective way to collect these samples.
What’s the plan?
Collect EEG data from patients, analyze data, determine a biomarker.
This grant proposes using EEGs to collect data on the brains of 20 Syngapians to then be analyzed in a second, related, grant to see if a biomarker could be made from that data. We need this data.
These 20 patients will be invited to either Boston Children’s Hospital or UCLA to complete two different EEGs, one year apart.
As part of the second grant, researchers will analyze the specific brain activity of SYNGAP1 patients, typically developing children, and patients with other synapse-related disorders to find activity that is unique to SYNGAP1.
Why is this a good investment?
It is catalytic: we are doing much more than funding EEGs and biosamples.
Who can participate?
Anyone signed up for Ciitizen!
Anyone enrolled in the 5p- Ciitizen Study can participate., if you are interested and willing please let CDCRF know. Being signed up for Ciitizen allows for patients’ full medical records to be readily available for analysis by researchers, and therefore available to be compared to the EEG/biofluid that is collected. You can sign up for Ciitizen at no cost at this link. We encourage all 5p- syndrome patients to be signed up for Ciitizen to help further 5p- syndrome research and get access to opportunities to participate in studies like this, as well as clinical trials in the future.
