▶Genetic Investigation Into the Differential Risk of Atrial Fibrillation Among Black and White IndividualsAssociationN=17,325Jason D. Roberts et al.(2016)· JAMA Cardiology
This genome-wide admixture analysis of three population-based cohorts (CHS, ARIC, Health ABC; n=17,325) investigated whether 9 known atrial fibrillation (AF) SNPs explain the paradoxically higher AF risk in Whites compared to Blacks. Using Cox proportional hazards models, rs10824026 (in SYNPO2L/MYOZ1) significantly mediated 11.4% (95% CI 2.9-29.9%) and 31.7% (95% CI 16.0-53.0%) of the excess AF risk in Whites in CHS and ARIC respectively. Admixture mapping across 4,938 Black participants identified no loci reaching genome-wide significance (p<7×10⁻⁶), suggesting the racial differential in AF risk is driven by multiple genetic and/or environmental factors rather than single variants.
About KCNN3
Action potentials in vertebrate neurons are followed by an afterhyperpolarization (AHP) that may persist for several seconds and may have profound consequences for the firing pattern of the neuron. Each component of the AHP is kinetically distinct and is mediated by different calcium-activated potassium channels. This gene belongs to the KCNN family of potassium channels. It encodes an integral membrane protein that forms a voltage-independent calcium-activated channel, which is thought to regulate neuronal excitability by contributing to the slow component of synaptic AHP. This gene contains two CAG repeat regions in the coding sequence. It was thought that expansion of one or both of these repeats could lead to an increased susceptibility to schizophrenia or bipolar disorder, but studies indicate that this is probably not the case. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2011]
