Tissue-specific expression and in vivo regulation of zebrafish orthologues of mammalian genes related to symptomatic hypomagnesemia.
Nijmegen, Netherlands. In Pflugers Arch, 31 Oct 2013
In humans, mutations related to hypomagnesemia are located in the genes TRPM6 and CNNM2, encoding for a Mg(2+) channel and transporter, respectively; EGF (epidermal growth factor); SLC12A3, which encodes for the Na(+)-Cl(-) co-transporter NCC; KCNA1 and KCNJ10, encoding for the K(+) channels Kv1.1 and Kir4.1, respectively; and FXYD2, which encodes for the γ-subunit of the Na(+),K(+)-ATPase.
Voltage-gated potassium channels and the diversity of electrical signalling.
San Francisco, United States. In J Physiol, Jul 2012
As one indication of the evolutionary conservation of Kv1 channel functions, mutations of the Shaker potassium channel gene in Drosophila and the KCNA1 gene for its mammalian orthologue, Kv1.1, cause hyperexcitability near axon branch points and nerve terminals, thereby leading to uncontrolled movements and recapitulating the episodic ataxia-1 (EA1) symptoms in human patients.
Episodic ataxias 1 and 2.
Los Angeles, United States. In Handb Clin Neurol, 2011
This study suggested that kcna1 missense mutation have been related to Episodic ataxias 1.
[Hereditary episodic ataxia].
Paris, France. In Rev Neurol (paris), 2011
EA1 is caused by mutations of the KCNA1 gene coding for the voltage-gated potassium channel Kv1.1.
Medulloblastoma comprises four distinct molecular variants.
Toronto, Canada. In J Clin Oncol, 2011
integrative genomics approach to a large cohort of medulloblastomas has identified four disparate subgroups (KCNA1)with distinct demographics, clinical presentation, transcriptional profiles, genetic abnormalities, and clinical outcome.
[Genetics components in patients with temporal lobe epilepsy].
Madrid, Spain. In Rev Neurol, 2009
We have reviewed the following genes; LGI1, PDYN (prodynorphin), interleucine 1beta, PRPN (prion protein), ApoE (apolipoprotein E), GABBR1, SCN1A, SCN1B, KCNA1, KCND2.
Recent advances in the genetics of recurrent vertigo and vestibulopathy.
Los Angeles, United States. In Curr Opin Neurol, 2008
RESULTS: Since the identification more than a decade ago of the genetic causes of episodic ataxia type 1 with myokymia caused by KCNA1 mutations and episodic ataxia type 2 with nystagmus caused by CACNA1A mutations, the list of episodic ataxia syndromes with distinct clinical features and genetic loci is slowly expanding, now up to episodic ataxia type 7.
