1. A method for determining a susceptibility to a condition selected from the group consisting of: cardiac arrhythmia selected from Atrial Fibrillation and Atrial Flutter, and Stroke, in a human individual, the method comprising: analyzing nucleic acid from a biological sample from the human individual for a T allele of a polymorphic marker rs7193343;detecting a T allele of rs7193343 in the nucleic acid;determining that the individual has an increased genetic susceptibility to a condition selected from the group consisting of: cardiac arrhythmia selected from Atrial Fibrillation and Atrial Flutter, and Stroke from the detection of the T allele of rs7193343 in the nucleic acid; andperforming an electrocardiogram or initiating anticoagulant therapy on the individual determined to have the increased susceptibility to the condition. 2. The method of claim 1, comprising analyzing the nucleic acid with respect to at least two polymorphic markers. 3. The method of claim 1, further comprising isolating the biological sample from the human individual. 4. The method of claim 1, wherein determination of a susceptibility comprises comparing sequence data obtained from the nucleic acid analysis to a database containing correlation data between the at least one polymorphic marker and susceptibility to the condition. 5. The method of claim 1, wherein the determining that the individual has the increased susceptibility includes calculating a risk score for the individual that includes an odds ratio and/or relative risk of at least 1.10 attributable to the detection of allele T of polymorphic marker rs7193343 in the nucleic acid. 6. The method of claim 1, further comprising reporting the susceptibility to at least one entity selected from the group consisting of the individual, a guardian of the individual, a genetic service provider, a physician, a medical organization, and a medical insurer. 7. The method of claim 1, wherein the condition is ischemic stroke. 8. The method of claim 7, wherein the ischemic stroke is cardioembolic stroke. 9. The method of claim 1, wherein the condition is Atrial Fibrillation or Atrial Flutter. 10. The method of claim 1, further comprising determining at least one biomarker in a sample from the individual, and determining combined risk based on susceptibility attributable to the detection of the T allele of 7193343 and susceptibility attributable to the at least one biomarker, using a multiplicative model. 11. The method of claim 10, wherein the biomarker is a protein biomarker selected from the group consisting of fibrin D-dimer, prothrombin activation fragment 1.2 (F1.2), thrombin-antithrombin III complexes (TAT), fibrinopeptide A (FPA), lipoprotein-associated phospholipase A2 (Ip-PLA2), beta-thromboglobulin, platelet factor 4, P-selectin, von Willebrand Factor, pro-natriuretic peptide (BNP), matrix metalloproteinase-9 (MMP-9), PARK7, nucleoside diphosphate kinase (NDKA), tau, neuron-specific enolase, B-type neurotrophic growth factor, astroglial protein S-100b, glial fibrillary acidic protein, C-reactive protein, serum amyloid A, matrix metalloproteinase-9, vascular and intracellular cell adhesion molecules, tumor necrosis factor alpha, and interleukins, including interleukin-1, -6, and -8. 12. The method according to claim 1, wherein the determining of the susceptibility is performed using a computer-readable medium having computer executable instructions for determining susceptibility to a condition selected from the group consisting of: a cardiac arrhythmia selected from Atrial Fibrillation and Atrial Flutter, and Stroke, the computer readable medium comprising: data indicative of at least one polymorphic marker that is rs7193343; anda routine stored on the computer readable medium and adapted to be executed by a processor to determine risk of developing the condition for the at least one polymorphic marker. 13. The method of claim 12, wherein the medium contains data indicative of at least two polymorphic markers. 14. The method according to claim 1, wherein the determining of the susceptibility is performed using an apparatus for determining a genetic indicator for a condition selected from the group consisting of: a cardiac arrhythmia selected from Atrial Fibrillation and Atrial Flutter, and Stroke, in a human individual, the apparatus comprising: a processor;a computer readable memory having computer executable instructions adapted to be executed on the processor to analyze marker information for at least one human individual with respect to at least one polymorphic marker that is rs7193343, and generate an output based on the marker information, wherein the output comprises a risk measure of susceptibility of the at least one marker as a genetic indicator of the condition for the human individual. 15.

The method according to claim 14, wherein the computer readable memory further comprises data indicative of the risk of developing the condition associated with at least one allele of the at least one polymorphic marker, and wherein a risk measure for the human individual is based on a comparison of the at least one marker status for the human individual to the risk of the condition associated with the at least one allele of the at least one polymorphic marker. 17. The method according to claim 14, wherein the computer readable memory further comprises data indicative of the frequency of at least one allele of the at least one polymorphic marker in a plurality of individuals diagnosed with the condition, and data indicative of the frequency of at the least one allele of the at least one polymorphic marker in a plurality of reference individuals, and wherein risk of developing the condition is based on a comparison of the frequency of the at least one allele in individuals diagnosed with the condition and reference individuals. 18. The method according to claim 14, wherein the risk measure is characterized by an Odds Ratio (OR) or a Relative Risk (RR). 19. The method according to claim 6, wherein the reporting comprises making the determination of susceptibility available to the at least one person via a secure website. 20.
