1.摘要
了解您的健康风险遗传倾向是预防和个性化医疗保健的有力工具。基因分析可以揭示您患上各种疾病（例如神经退行性疾病）的可能性。这项测试探索了基于您的基因构成的健康风险分析如何指导积极的健康策略、早期干预和个性化医疗，从而改善长期健康状况。
2.背景
为什么有些人尽管生活方式健康，却似乎患上了某些疾病，而另一些人却毫发无损？答案往往在于我们的基因。基因在决定我们患上神经退行性疾病、心脏病、糖尿病甚至某些癌症的风险方面起着关键作用。通过基因检测进行健康风险分析，可以让我们识别自己对这些疾病的易感性，并在其显现之前采取措施进行预防。
虽然我们无法改变基因，但了解自己的遗传风险，可以帮助您在生活方式和医疗保健方面做出明智的决定。有了这些知识，您就可以调整饮食、运动和医疗筛查，从而降低罹患这些疾病的可能性，过上更健康、更长寿的生活。
3.技术概述
· SNP分析：单核苷酸多态性 (SNP) 是指DNA中的微小变异，可能会影响您患某些疾病的可能性。基因检测可以识别这些 SNP，并基于大规模全基因组关联研究 (GWAS) 将其与已知的健康风险进行关联分析。
· 多基因风险评分：对于心脏病或糖尿病等复杂疾病，多个基因都会影响总体风险。多基因风险评分综合了多种基因变异的影响，让您更清晰地了解您的总体风险。
· 预测健康模型：通过将基因数据与环境和生活方式因素相结合，预测模型可以更全面地了解您的潜在健康结果。这种整体方法能够更准确地预测风险并制定个性化的预防措施。
4. 主要发现
· 神经系统疾病：载脂蛋白E（APOE）等基因（特别是APOE-e4变体）与阿尔茨海默病有关。如果您罹患神经退行性疾病的遗传风险较高，早期进行认知筛查和调整生活方式（例如促进大脑发育的饮食和脑力锻炼）有助于延缓或减轻症状的严重程度。
5. 应用
· 个性化预防保健：了解您的遗传风险，您可以采取积极主动的措施来管理您的健康。无论是定期筛查、改变生活方式还是药物治疗，您都可以与医疗保健提供者合作，制定个性化计划，以降低您的特定健康风险。
· 早期发现：基因检测可以在症状出现之前就识别出您的疾病易感性。早期发现可以及时干预，例如增加筛查频率或调整饮食和运动，从而在潜在问题变得严重之前发现它们。
All 6.4 billion letters of your DNA — read, stored, and yours to keep.
Most consumer DNA tests sample a few hundred thousand positions. Whole genome sequencing reads the entire thing at 30× depth, and hands you the files at the end. No subscription required to keep them.

How it runs
Kit arrives
Day 0，Saliva collection takes about five minutes. Avoid eating, drinking, or brushing your teeth for thirty minutes beforehand — that's the only preparation required.
Sample ships back
Day 1–2， Prepaid return envelope is included. Saliva samples are stable at room temperature, so there's no cold chain to manage on your end.
DNA extraction and quality check
Week 1，We extract and assess DNA quality before sequencing. If a sample fails QC, we send a replacement kit at no charge rather than sequencing something that won't yield reliable calls.
Sequencing and analysis
Week 2–6，Sequencing, alignment to GRCh38, and variant calling. This is the longest stage and we'd rather state it accurately than quote a number we miss.
Reports and files released
Week 2–6， Your reports and all three file formats become available together. You'll get an email the moment they're ready.
No. Ebogenes whole genome sequencing is offered for research and personal informational use. It is not a diagnostic test, it is not a substitute for clinical genetic testing, and it should not be used to make medical decisions on its own. If a finding concerns you, bring it to a physician or a certified genetic counsellor — that's what the files are for.
Each position in your genome is read approximately thirty times on average. Sequencing makes errors, so reading a position once tells you little; reading it thirty times lets a variant call rest on consensus. 30× is the widely used standard for reliable variant calling — below it, calls get noticeably less dependable.
Our reports flag findings for follow-up; they do not diagnose. A variant of uncertain significance is a flag, not a finding — many are later reclassified as benign. We'd rather tell you plainly that something needs a professional look than dress up an uncertain result as an answer.
Sequencing and storage happen at our Laval, Québec facility. Your data stays in Canada and is subject to Canadian privacy law. We do not sell your genetic data, and we do not share it with insurers, employers, or research programmes without your explicit, separate consent. You can request deletion at any time.
No. Your reports and all three file formats remain accessible without any ongoing payment. Download them and store your own copy if you prefer — that's the point of giving you FASTQ.
