Gene RIF (17)

26997484 Kv3.3 regulates Arp2/3-dependent cortical actin nucleation mediated by Hax-1; resulting cortical actin structures interact with the channel's gating machinery to slow its inactivation rate during sustained membrane depolarizations; a mutation that leads to late-onset spinocerebellar ataxia type 13.
26849432 The Kv channels, or at least Kv3.3, appear to be associated with cell differentiation
25981959 investigated using either targeted next generation sequencing or trio-based exome sequencing and were found to have mutations in three different genes, KCNC3, ITPR1 and SPTBN2
25756792 Functional and in silico analysis identified at least one novel pathogenic mutation in KCNC3 that cause Spinocerebellar ataxia type 13 (SCA13) and two additionally potential ones.
25152487 These results are specific to the KCNC3(R420H) allele and provide new insight into the molecular basis of disease manifestation in SCA13.
24116147 Data indicate that an autosomal dominant mutation in the gene encoding Kv3.3 has been identified in a large Filipino kindred manifesting as spinocerebellar ataxia type 13 (SCA13).
23912307 This study presented the results of a detailed neurological clinical and diagnostic testing on 21 mutation-positive members of a four-generation Filipino family to further define this disease, aiding diagnosis and prognosis.
23734863 Data suggest that mutant forms of Kv3.3 (as seem in subjects with spinocerebellar ataxia-13) are unstable, are degraded through proteasomes at faster rates, and can be stabilized by a chemical chaperone.
23293936 no disease-related KCNC3 mutation was identified, suggesting that spinocerebellar ataxia type 13 is a rare form of SCA in mainland China
22289912 Kv3.3 gating contributes significantly to an early age of onset in spinocerebellar ataxia type 13
21827913 The KCNC3 mutation casued Spinocerebellar ataxia 13.
21543613 The spinocerebellar ataxia type 13 mutation of the KV3.3 gene specifically suppresses the excitability of Kv3.3-expressing, fast-spiking neurons in zebrafish
21479265 Mutations in KCNC3 are a rare cause of spinocerebellar ataxia with a frequency of less than 1%.
19953606 The p.Arg420His mutation, which results in a nonfunctional channel subunit, was recurrent and associated with late-onset progressive ataxia.
18592334 Mutations in the voltage-gated potassium channel KCNC3 are causative for spinocerebellar ataxia 13.
16501573 results establish a role for KCNC3 in phenotypes ranging from developmental disorders to adult-onset neurodegeneration and suggest voltage-gated K+ channels as candidates for additional neurodegenerative diseases
