Genes affected
CHD2 (HGNC:1917): (chromodomain helicase DNA binding protein 2) The CHD family of proteins is characterized by the presence of chromo (chromatin organization modifier) domains and SNF2-related helicase/ATPase domains. CHD genes alter gene expression possibly by modification of chromatin structure thus altering access of the transcriptional apparatus to its chromosomal DNA template. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

CHD2-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesApr 14, 2023The CHD2 c.3982_3984delAAG variant is predicted to result in an in-frame deletion (p.Lys1328del). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/15-93541819-GAGA-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Developmental and epileptic encephalopathy 94 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeAug 10, 2023This variant, c.3982_3984del, results in the deletion of 1 amino acid(s) of the CHD2 protein (p.Lys1328del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with CHD2-related conditions. ClinVar contains an entry for this variant (Variation ID: 474389). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
