Cure CHD2

Models of CHD2

As part of our "Roadmap to a Cure", we must ensure that any treatment we intend to use in people will be safe, efficacious and has the greatest potential to benefit people living with a CHD2 mutation.

For these reasons, developing models of CHD2 that can be widely shared with the fewest barriers or commercially purchased is a top priority for our community.

Listed below is a growing list of models that can be used as tools for basic biology and translational-preclinical studies of CHD2.

iPSC

PFIZi029-A Description: c4636 C>T in exon 36 of the CHD2 gene (NM_001271.3)

CHD2 human stable knockdown cell lines through AcceGen Biotech

Human CHD2 shRNA knockdown in HEK293 or HeLa cells

CHD2 mouse model that has 2 nucleotide deletion in the 3rd exon of CHD2, which leads to production of little to no CHD2 protein.

Dr. Igor Ulitsky has a mouse model that has 2 nucleotide deletions in the 3rd exon of CHD2, which leads to production of little to no CHD2 protein. See his paper for more details: https://www.nature.com/articles/s41467-019-13075-8.pdf

Ongoing Studies

RARE-X Study

Participating in a data collection program is one of the most important things that families with a child with CHD2-related neurodevelopmental disorders can do.

CHD2 In Adults

This study aims to understand seizures, communication and daily living of adults with CHD2 mutations.

Citizen Health

Natural History Studies (NHS) are critical to the drug development process. Citizen Health has developed a new method to make this process easier.
