My Identical Twin Sequenced our Genome.

Author information

Abstract

With rapidly declining costs, whole genome sequencing is becoming feasible for widespread use. Although cost-effectiveness is driving increased use of the technology, comprehensive recommendations on how to handle ethical dilemmas have yet to reach a consensus. In this article, Sam shares her experience of undergoing whole genome sequencing. Despite the deeply private nature of the test, the results do not solely belong to Sam; her identical twin sister, Arielle, shares virtually the same genome and received results without a formal consent process. This article explores their parallel experiences as a way of highlighting the controversial ethics of a private test with familial implications.
