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 an A to G transition at position 1057 of the Chd2 transcript in exon 6 of 39 total exons. The mutated nucleotide causes a glutamine to arginine substitution at amino acid 162 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 proteinthat 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 Q162R change is predicted to be benign by the PolyPhen program.
