MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Mice homozygous for a gene trap allele exhibit early postnatal lethality associated with fetal growth retardation. Mice heterozygous for a gene trap allele exhibit postnatal lethality and premature death after weaning associated with growth retardation and multi-organ defects. [provided by MGI curators]

Nature of Mutation
DNA sequencing using the SOLiD technique identified a T to G transversion at position 4216 of the Chd2 transcript in exon 29 of 39 total exons. The mutated nucleotide causes a valine to glycine substitution at amino acid 782 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).
Protein Function and Prediction
The Chd2 gene encodes an 1827 amino acid protein that is a DNA-binding/helicase protein. CHD2 contains two Chromo domains at amino acids 260-346 and 376-449 (SMART).  These domains are found in proteins that alter chromatin structure. The protein also contains a DEXDc domain at amino acids 480-677, and other domains at amino acids 821-905 and 960-1244 typically found in helicases. Mice homozygous for a gene trap allele exhibit early postnatal lethality associated with fetal growth retardation. Mice heterozygous for a gene trap allele exhibit postnatal lethality and premature death after weaning associated with growth retardation and multi-organ defects.  
 
The V782G change is predicted to be benign by the PolyPhen program.
