Parenthood changes one's perspective and focus. Myriad things that previously seemed benign, such as escalators, shopping carts, and even forks, now represent imminent danger. Like biological parent-child relationships, adoptive parent-child relationships come in many forms, sometimes good and sometimes bad. I am lucky: My bond with my daughter is strong. I see her light up when I enter the room, and I feel myself light up over something as simple as someone turning the conversation to how she is doing. My world now revolves around her. The focus of my life has become her happiness and well-being and protecting her from harm and sadness. I want to shape the world in her favor: Where I perceive her to lack something that might benefit her, the urge to fill that gap for her benefit is among the strongest influences I have ever felt.One gap that is constantly present for many adoptive parents (especially for parents of children, like my daughter, who are adopted internationally) is the inability to provide sophisticated genetic heritage information. In my own experience, we were provided with little more than a photograph, and a vague statement that the child appears healthy, as the "medical" portion of our information packet (the rest of the packet focused on personality, temperament, and behavioral traits). We were told that she received basic vaccinations, but lack of verifiable documentation and concerns about reliability resulted in pediatricians in the United States providing vaccinations as if she had not received them before. We are unaware of any newborn screening as might be done in the United States, nor do we believe such screening occurred. Indeed, we have no information about illnesses that run in her biological family from either side. I can relate, then, to the emotions behind adoptive parents' advocacy of genetic testing as a way to fill a gap in their child's biological heritage, be it for information about medical conditions they may be prone to or for facts about where their child came from. Although the emotions underlying the desire to fill informational gaps are definitely not unique to adoptive parents, their manifestation in the potential uptake of genetic testing relates, at least for some adoptive parents (like me), to the circumstances of genetic unrelatedness.I believe that many, if not most, adoptive parents are aware of the 23andMe genetic testing service. 23andMe has offered 2 distinct types of testing services: testing related to ancestry and a personal genomic
