Summaries for EFHC1 Gene

Entrez Gene Summary for EFHC1 Gene

  • This gene encodes an EF-hand-containing calcium binding protein. The encoded protein likely plays a role in calcium homeostasis. Mutations in this gene have been associated with susceptibility to juvenile myoclonic epilepsy and juvenile absence epilepsy. Alternatively spliced transcript variants have been described. [provided by RefSeq, Feb 2010]

GeneCards Summary for EFHC1 Gene

EFHC1 (EF-Hand Domain Containing 1) is a Protein Coding gene. Diseases associated with EFHC1 include Myoclonic Epilepsy, Juvenile 1 and Epilepsy, Juvenile Absence 1. GO annotations related to this gene include calcium ion binding and protein C-terminus binding. An important paralog of this gene is EFHC2.

UniProtKB/Swiss-Prot for EFHC1 Gene

  • Necessary for radial and tangential cell migration during brain development, possibly acting as a regulator of cell morphology and process formation during migration (PubMed:22926142). May enhance calcium influx through CACNA1E and stimulate programmed cell death (PubMed:15258581).

  • Juvenile absence epilepsy 1 (JAE1) [MIM:607631]: A subtype of idiopathic generalized epilepsy characterized by onset occurring around puberty, absence seizures, generalized tonic-clonic seizures (GTCS), GTCS on awakening, and myoclonic seizures. {ECO:0000305 PubMed:17159113}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
  • Juvenile myoclonic epilepsy 1 (EJM1) [MIM:254770]: A subtype of idiopathic generalized epilepsy. Patients have afebrile seizures only, with onset in adolescence (rather than in childhood) and myoclonic jerks which usually occur after awakening and are triggered by sleep deprivation and fatigue. {ECO:0000269 PubMed:15258581, ECO:0000269 PubMed:17634063, ECO:0000269 PubMed:22690745, ECO:0000269 PubMed:22727576}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
  • Note=Mutation Leu-229 may be a cause of intractable epilepsy of infancy. Affected individuals have seizures of multiple type, manifested as tonic, clonic, and myoclonic seizures in the neonatal period, and as tonic seizures activated frequently by sleep, and repeated frequent myoclonic seizures in later infancy. The seizures are unresponsive to numerous antiepileptic drugs, and infants die in the first years of life. Although heterozygosity for Leu-229 has been associated with relatively benign forms of epilepsy in adolescence, homozygosity for the same mutation has much more severe consequences. {ECO:0000269 PubMed:22690745}.
