Summaries for EFHC2 Gene

Entrez Gene Summary for EFHC2 Gene

  • This gene encodes a protein which contains three DM10 domains and three calcium-binding EF-hand motifs. A related protein is encoded by a gene on chromosome 6. It has been suggested that both proteins are involved in the development of epilepsy (PMID: 15258581, 16112844) and that this gene may be associated with fear recognition in individuals with Turner syndrome. [provided by RefSeq, Aug 2011]

GeneCards Summary for EFHC2 Gene

EFHC2 (EF-Hand Domain Containing 2) is a Protein Coding gene. Diseases associated with EFHC2 include Turner Syndrome. GO annotations related to this gene include calcium ion binding. An important paralog of this gene is EFHC1.
