SCN5A R34Cinsufficiently evaluated benign, f=0.031unknown

SNC5A is the cardiac sodium channel gene. Mutations in this gene have been associated with idiopathic ventricular fibrillation and Burgunda Syndrome, however, the R34C mutation of the gene has been largely identified as benign with no noticeable phenotypic effect.

Although this gene is associated with acquired Long-QT syndrome (alQTS) Yang et al. found no difference in the frequency of this variant in alQTS patients and controls (3% versus 3%).

SCN5A G615Epathogenic, f=0.000dominant

Rare, reported to be associated with long-QT syndrome (can cause syncopal spells, sudden death as a teenager / young adult), but observations are scattered may have some publication bias.

SCN5A P627Lpathogenicdominant

Reported by ClinVar to cause disease (https://www.ncbi.nlm.nih.gov/clinvar/variation/201577/). The condition is unspecified in ClinVar, but other variants in this gene cause dominantly-inherited heart diseases, including Brugada syndrome, familial dilated cardiomyopathy, and Romano-Ward syndrom.

In ClinVar this variant is reported as “pathogenic” by GeneDx. However, it is classified as “uncertain significance” by the Stanford Center for Inherited Cardiovascular Disease. Neither ClinVar submission includes references to published literature. The frequency of this variant is extremely rare according to ExAC data (http://exac.broadinstitute.org/variant/3-38645213-G-A).

SCN5A V789Iuncertain benignunknown

Reported to cause Brugada syndrome (increased risk of sudden cardiac death), but the reported observation doesn’t different from the variant’s general allele frequency. Kapplinger et al. 2009 reported seeing this variant once in 2,111 patients and not in 1,300 controls. ExAC reports the variant present in 9 out of 33,201 individuals with European ancestry (1 in 3,700). This allele frequency indicates the reported observation was almost certainly coincidental as it is consistent with ExAC’s allele frequency for the general population. Brugada syndrome is estimated to affect 1 in 2,000; if this variant were causal with any notable penetrance, it would be found in a large fraction of patients. Based on updated allele frequency information data, this hypothesis should be considered disproven.

SCN5A S1103Yinsufficiently evaluated pathogenic, f=0.016other

This is a common variant in individuals of African descent (African American allele frequency 6.8%). It is associated with an increased risk of cardiac arrhythmia (odds ratio of 8.7 for both homozygous and heterozygous carriers) and of sudden infant death syndrome (24-fold increase for homozygous).

SCN5A R1193Qlikely pathogenic, f=0.008dominant

Proposed as a dominant cause of rare heart arrhythmia diseases (Brugada Syndrome and Long QT Syndrome). This has since been contradicted by the high frequency of this variant in the Han Chinese population. 14% of Chinese are carriers, contradicting this variant as a high penetrance cause of rare disease. It is possible the variant is associated with low increased risk of Long QT syndrome, but this is a speculative and untested hypothesis.
