Genetic Rounds: A Doctor's Memorable Encounters in the Field That Has Revolutionized Medicine

Robert Marion. Kaplan, $26.95 (278pp) ISBN 978-1-60714-460-1

Although he's often uncomfortable about it, as a clinical geneticist, Marion (The Intern Blues ) examines his patients' genetic secrets—information they sometimes don't reveal even to close relatives—in order to help them make family planning decisions . His ability to solve medical mysteries can be a blessing: after a mother is accused of child abuse, Marion is able to use genetic analysis to diagnose brittle bone disease in the baby and to help return the infant to her mother. But his diagnostic skills become a curse when he tells his former college roommate that his toddler isn't just a slow starter but likely has Bardet-Biedl syndrome: the enraged friend never speaks to Marion again. In a headline-making case, he tries to explain why a pair of twins joined at the head lack speech. Although his short pieces lack the depth and finesse of essays by other physician-writers like Oliver Sachs, and Marion's case studies would frighten even the steeliest of would-be parents, Marion, director of clinical genetics at Montefiore Medical Center and Blythedale Children's Hospital in New York State, is a sympathetic advocate for his patients who lucidly interprets complex medical conditions for lay readers.
