Genes affected
CLCN2 (HGNC:2020): (chloride voltage-gated channel 2) This gene encodes a voltage-gated chloride channel. The encoded protein is a transmembrane protein that maintains chloride ion homeostasis in various cells. Defects in this gene may be a cause of certain epilepsies. Four transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2012]
FAM131A (HGNC:28308): (family with sequence similarity 131 member A)
