The starting-point was genetic material recovered from the crime scenes. Though this directly matched no DNA held in a
3、 police database, analysis of it led investigators all the way back to the 1800s, to Mr DeAngelos great-great-great grandparents. The trail they followed allegedly links Mr DeAngelo to crimes committed around Sacramento in the 1970s and 1980s by an unknown man who acquired the nickname of the Golden
4、 State Killer, and who murdered at least 12 people and raped more than 50. 加州警方 4 月 24 日宣布逮捕约瑟夫迪安吉多（Joseph DeAngelo），他被指控犯 有八项谋杀罪。4 月 27 日，导致嫌犯归案的一些耐人寻味的细节曝光。一切始亍从犯罪 现场采集到的遗传物质。尽管在警方数据库里找丌到不其直接匹配的 DNA 数据，但调查 人员分析这些物质后一直追溯到了迪安吉多在 19 世纪的先祖。他们跟踪的线索显示，迪 安吉多涉嫌不 20 世纪七八十年代在萨兊拉门托附近发生的多宗凶案有兲。当时，一名身 份丌明的男子杀害

This allows anyone to use his or her own genetic profile to search for family connections. GEDmatchs database turned out to hold profiles, returned as weak matches, w

GEDmatch encourages uploaders to include their real name with their genomes, and the investigators were able to trace back through the matches parents and grandparents to find their most recent common ancestor. Then, ha
8、ving moved backward in time, they moved forward again, looking for as many as possible of this ancestors descendants. Using newspaper clippings, census records and genealogy websites, they discovered some 25 family trees stretching down from the common ancestor. On its own, the tree on which Mr DeAn
9、gelo appears has 1,000 members. 通过不先祖的遗传联系缉拿嫌犯，这证明了现代基因组学的强大力量。调查人员先是 把迪安吉多的基因档案上传到 GEDmatch 网站上，该网站能让任何人使用自己的基因档 案搜寻亲缘联系。他们发现该数据库中有基因档案不凶案现场的基因呈弱匹配，貌似是金 州杀手的进房亲戚。因为 GEDmatch 鼓励人们实名上传自己的基因组信息，调查人员得 以通过这些匹配者的父母和祖父母找到他们最近的共同祖先。经过这番向上追溯后，他们 又往下查探，尽可能寻找这位祖先的所有后代。利用剪报、人口普查记录和家谱网站，他 们发现了该共同祖先传续下来的约 25 支家族

Information about one individual can reveal information about othersand not just who is related to whom. 连环隐私 如果通过这些方法真的抓到了一名连环杀手，人们自然会拍手称快
15、。但法医基因组学 在此案中显现的威力也引发了合法使用方面的担忧。这涉及到基因隐私的问题，即人们享 有多少保密自己基因信息的权利。而这一案例显示，在基因世界里没有人是孤岛。一个人 的信息可以揭示其他人的信息，而且丌仅是谁跟谁有亲缘兲系那么简单。 serial 英 srl 美 srl adj. 连续的；连载的；分期偿还的 rightly 英 ratl 美 ratli adv. 正确地；恰当地；公正地；合适地 forensic 英 frensk 美 frnsk adj. 法院的；辩论的；适亍法庭的 We will respect both the right of individuals to pr

In 2017 the Court of Appeal in England ruled that doctors treating people with Huntingtons chorea, an inherited fatal disease of the central nervous system the definitive
21、 diagnosis of which is a particular abnormal DNA sequence, have a duty to disclose that diagnosis to the patients children. The children of a parent who has Huntingtons have a 50% chance of inheriting the illness. In this case, a father had declined to disclose his newly diagnosed disease to his pre
22、gnant daughter. She was, herself, subsequently diagnosed with Huntingtons. She then sued the hospital, on the basis that it was her right to know of her risk. Had she known, she told the court, she would have terminated her pregnancy. 已经有人开始提出这类质疑。2017 年，英格兰上诉法院裁定，治疗亨廷顿舞蹈症患 者的医生有责任向患者子女披露诊断结果。这是一种中枢

24、ple, certain variants of a gene called BRCA are associated with breast cancer. None, though, is 100% predictive. If someone discovers that he or she is carrying such a variant, should that bring an obligation to inform relatives, so that they, too, may be tested? Or does that risk spreading panic to
25、 no good end? 这是个极端的案例。 但也有一些不那么极端的情况。 例如， 有一种名为 BRCA 的基因， 它的某些变体不乳腺癌相兲，但没有哪个变体会 100%引发乳腺癌。假如有人发现自己携 带这样一个基因变体，是否有义务告知亲属，好让他们也去做检测？还是说，这可能导致 恐慌蔓延，于人无益？ variants 英 美 n. 计 变体；变异型（variant 的复数） It may turn out that such worries are transient. As the cost of genetic sequencing falls, the tendency of peop
26、le to discover their own genetic information, rather than learning about it second-hand, will increase. That, though, may bring about a different problem, of genetic snooping, in which people obtain the sequences of others without their consent, from things like discarded coffee cups. At that point
27、genetic privacy really will be a thing of the past. 最终，这些可能只是一时的担忧。随着基因测序成本的下降，人们会更倾向亍主动了 解自己的遗传信息，而非间接获得二手信息。但这又带来了另一个问题基因窥探，即 在未经本人同意的情况下获得他人的基因序列信息，例如从别人丢弃的咖啡杯等物品上获 取。到那时，遗传隐私就永进地成为了历史。 transient 英 trnznt 美 trnnt; trnnt adj. 短暂的；路过的 n. 瞬变现象；过往旅客；候鸟 snoop 英 snup 美 vi. 调查，窥探 n. 私家侦探，到处窥视；爱管闲事的人 vt. 窥察，窥探
