On this page, you will find information about a genetic change that was identified in a UDN participant. We are trying to find others with the same or similar condition.

Sharing information on this website is not a requirement of UDN participation. Only descriptions about participants who give explicit consent will appear here.

A change in this gene was identified in a female, age 5, with brain abnormalities, flow of urine from bladder to kidneys (vesicoureteral reflux), global developmental delay and atrial septal defect (read full description).

Date of Report

Sep 28, 2021

Full Name

chromodomain helicase DNA binding protein 2

Chromosome 15 (15q26.1)


The CHD2 gene codes for a member of the chromodomain helicase DNA-binding family of proteins. These proteins regulate gene expression through chromatin remodeling (Carvill et al., 2013).

Clinical Significance

Changes in the CHD2 gene have been found in individuals with childhood-onset epileptic encephalopathy (OMIM).

The following de novo genetic change was also identified in a UDN participant. In addition to this change, there is a nearby deletion of the non-coding gene CHASERRThese changes may cause overexpression of CHD2 leading to the participant’s symptoms.
