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.

CHD2 human iPSC line available through the European Bank for Induced Pluripotent Stem Cells

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.
