Genes affected

CHD5 (HGNC:16816): (chromodomain helicase DNA binding protein 5) This gene encodes a member of the chromodomain helicase DNA-binding protein family. Members of this family are characterized by a chromodomain, a helicase ATP-binding domain and an additional functional domain. This gene encodes a neuron-specific protein that may function in chromatin remodeling and gene transcription. This gene is a potential tumor suppressor gene that may play a role in the development of neuroblastoma. [provided by RefSeq, Feb 2012]

The c.5815A>G (p.I1939V) alteration is located in exon 40 (coding exon 40) of the CHD5 gene. This alteration results from a A to G substitution at nucleotide position 5815, causing the isoleucine (I) at amino acid position 1939 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
