Genes affected

CLIC2 (HGNC:2063): (chloride intracellular channel 2) This gene encodes a chloride intracellular channel protein. Chloride channels are a diverse group of proteins that regulate fundamental cellular processes including stabilization of cell membrane potential, transepithelial transport, maintenance of intracellular pH, and regulation of cell volume. This protein plays a role in inhibiting the function of ryanodine receptor 2. A mutation in this gene is the cause of an X-linked form of cognitive disability. [provided by RefSeq, Jul 2017]

The c.641G>A (p.R214H) alteration is located in exon 6 (coding exon 6) of the CLIC2 gene. This alteration results from a G to A substitution at nucleotide position 641, causing the arginine (R) at amino acid position 214 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
