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.7085T>G (p.L2362R) alteration is located in exon 35 (coding exon 34) of the CHD6 gene. This alteration results from a T to G substitution at nucleotide position 7085, causing the leucine (L) at amino acid position 2362 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
