  • 功能：
    This protein mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient. It is a tetrodotoxin-resistant Na(+) channel isoform. This channel is responsible for the initial upstroke of the action potential. Channel inactivation is regulated by intracellular calcium levels.

    1. We identified a genetic variant that is associated with local anesthetic resistance in the gene encoding for Nav1.5. We also demonstrate that Nav1.5 is present in human peripheral nerves to support the plausibility that an abnormal form of the Nav1.5 protein could be responsible for the observed local anesthetic resistance. Specifically, we noted the A572D mutation in the SCN5A gene encoding for Nav1.5. PMID: 27243970
    2. Results demonstrate a novel pleiotropic phenotype arising from the compound SCN5A mutation, P1332L and A647D. The lethal LQT3 phenotype of P1332L was mitigated with the Brugada- associated A647D, which negated the previously reported therapeutic benefit of mexiletine. Concurrently, the A647 mutant reduced Na current sufficiently to produce a novel global cardiac conduction defect affecting the atria and ventricles. PMID: 29791480
    3. Study data suggest that SAR1A and SAR1B are the critical regulators of trafficking of Nav1.5. Moreover, SAR1A and SAR1B interact with MOG1, and are required for MOG1-mediated cell surface expression and function of Nav1.5. PMID: 30251687

    19. These results demonstrated that readthrough-enhancing methods effectively suppressed nonsense mutations in SCN5A and restored the expression of full-length channels.channels. However, the restored channels may increase the risk of arrhythmia PMID: 28552050
    20. Expression of the adult and fetal isoforms of SCN5A in human induced pluripotent stem cell derived-cardiomyocytes depends on the time in culture and affects the phenotypic assessment of mutations in these cells. PMID: 28739862
    21. The LAT may help distinguish true LQT3-causative mutations from an otherwise noncontributory VUS. Given that lidocaine acts as a late sodium current blocker, a positive LAT may enable the early identification of a pathological accentuation of the late sodium current that could be targeted therapeutically. PMID: 28412158
    22. These results further support the proposition that nNav1.5 is a novel biomarker of metastatic breast cancer PMID: 28698102

    24. These sudden infant death syndrome (SIDS)-related variants caused a severely dysfunctional Nav1.5 channel, which was mainly due to trafficking defects caused by the Q1832E mutation. The decreased current density is likely to be a major contributing factor to arrhythmogenesis in Brugada syndrome and the sudden death of this SIDS victim. PMID: 28370132

    27. A 12-lead ECG can be used to predict arrhythmias in SCN5A D1275N mutation carriers. The 12-lead electrocardiogram may reveal cardiac abnormalities before clinical symptoms occur. Electrocardiogram findings - initial QRS fragmentation, prolonged S-wave upstroke as well as supraventricular arrhythmias - were frequently encountered in all SCN5A D1257N mutation carriers. PMID: 28294644
    28. Novel Single Nucleotide Polymorphism at SCN5A implicate gene regulatory dysfunction in QT prolongation in African and Hispanic Americans. PMID: 27988371

    35. identified two novel native phosphorylation sites in the C terminus of NaV1.5 that impair FGF13-dependent regulation of channel inactivation and may contribute to CaMKIIdeltac-dependent arrhythmogenic disorders in failing hearts. PMID: 28882890
    36. Pathogenic variants in the SCN5A gene modify electrical excitability of sodium cannel that causes an imbalance in the currents of the different ions involved in the contraction process of the cardiomyocytes and induce ventricular remodeling and Dilated cardiomyopathy. PMID: 27736720
    37. Almost 2% of ARVD/C patients harbour rare SCN5A variants. For one of these variants, we demonstrated reduced sodium current, Nav1.5 and N-Cadherin clusters at junctional sites.

    44. Mutational analysis across all 29 exons in SCN5A of the proband and first-degree relatives of the family revealed that the proband inherited a compound heterozygote mutation in SCN5A, specifically p.A226V and p.R1629X from each parent. The study is the first to report a SCN5A compound heterozygote in a Singaporean Chinese family. PMID: 25829473
