Genes affected

CHD6 (HGNC:19057): (chromodomain helicase DNA binding protein 6) This gene encodes a member of the SNF2/RAD54 helicase protein family. The encoded protein contains two chromodomains, a helicase domain, and an ATPase domain. Several multi-subunit protein complexes remodel chromatin to allow patterns of cell type-specific gene expression, and the encoded protein is thought to be a core member of one or more of these chromatin remodeling complexes. The encoded protein may function as a transcriptional repressor and is involved in the cellular repression of influenza virus replication. [provided by RefSeq, Jul 2013]

The c.7897G>A (p.G2633S) alteration is located in exon 37 (coding exon 36) of the CHD6 gene. This alteration results from a G to A substitution at nucleotide position 7897, causing the glycine (G) at amino acid position 2633 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
