12 Working Nurse l WorkingNurse.com Celebrating National Nurses Week April 29–June 10, 2019 BOOK CLUB by Christine Contillo, RN, BSN, PHN T he widespread availability of commercial DNA testing is another modern scientific won- der that we're already starting to take for granted. It's become routine: Just spit in a tube, send it away and wait for the report. I've done it myself. Such testing is now so easy and com- monplace that we may be caught off- guard by the potentially life-alerting results. What you thought would be a harmless way to learn what countries your ancestors came from might instead reveal that your family's stories were just that: stories. In her new memoir, Inheritance, author Dani Shapiro talks about how an o)and comment by her mother sent her down the rabbit hole, beginning a strange odyssey of genetic testing, lies and family secrets. Shapiro's quest began with her moth- er's strange remark that Dani "was con- ceived" in Philadelphia, a city where her parents do not live. It didn't take long for Shapiro to bring her journalistic skills to bear on the question and discover that she was conceived through artificial insemina- tion, something to which she is sure her Orthodox Jewish father would have only reluctantly agreed. I won't spoil any of the twists and turns of this very bumpy ride, but I will say that along the way, we learn much about DNA, artificial insemination and how modern families conduct themselves. A Question of Identity Among her many books, Shapiro counts more than a few memoirs — this is her fifth. The common thread running through all of them is her desire to under- stand her place in the world and, on a smaller level, her place in her own blended family. This book finally answers some of her lingering questions, like why she is the one blond-haired, blue-eyed Jewish girl in a family with almost universally dark hair and dark eyes. For Dani, and I'm sure for many other people, DNA analysis can create as many questions as it answers. If we're not who we thought we were, then who are we, exactly? If the people we believed to be our family are not our biological kin, then what holds us together? Whom do we trust? Whom do we love? I found Inheritance fascinating enough to explore Shapiro's other memoirs. Some may consider her continued self-examina- tion excessive, but I find it intriguing, pos- sibly because I have also discovered some long-held secrets in my own family. Commercial DNA testing is another reminder that the future doesn't always wait for us to sort out the ethical implica- tions of our discoveries and innovations. Inheritance doesn't purport to have the answers, but shows us how unexpectedly profound — and sometimes devastating — those implications can be.
