Genes affected

CLIC6 (HGNC:2065): (chloride intracellular channel 6) This gene encodes a member of the chloride intracellular channel family of proteins. The gene is part of a large triplicated region found on chromosomes 1, 6, and 21. Alternative splicing results in multiple transcript variants encoding different isoforms.
