Genes affected
EFHC1 (HGNC:16406): (EF-hand domain containing 1) 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]
EFHC1 Gene-Disease associations (from GenCC):
  • juvenile myoclonic epilepsy
    Inheritance: AD Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)
