Homo sapiens

Also known as CLC2; ECA2; ECA3; EGI3; EGMA; EJM6; EJM8; CIC-2; EGI11; HALD2; LKPAT; clC-2

Gene ID: 1181 | Gene type: protein coding

About CLCN2

Cytogenetic location: 3q27.1 Genomic coordinates (GRCh38): 3:184,346,185-184,361,605 (from NCBI)

This gene has 22 transcripts (splice variants), 233 orthologues, 8 paralogues and is associated with 7 phenotypes. Broad expression in testis (RPKM 8.7), colon (RPKM 7.2) and 24 other tissues.

Summary

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]
