Chapter 7 - The DNA Age

Picking up threads from Chapter 3, the chapter tells of the progress in medical genetics, with the work of Harry Ostrer typifying the contributions of Jewish scientists. BRCA1 and 2, the breast-cancer mutations, are discovered in the mid-1990s. The 185delAG mutation poses a quandary for Jewish women, and they move to the forefront of DNA testing. Meanwhile, the Medina family grapples with the gene in a halting fashion.
