By Linda Geddes A TECHNIQUE that can spot faulty genes in embryos without having to identify the specific mutation could vastly broaden the scope of screening for inherited genetic disease. The method, which adapts a DNA fingerprinting technique used in forensic testing, could also result in more healthy IVF embryos for implantation in the womb. Pre-implantation genetic diagnosis (PGD) involves taking a single cell from an IVF embryo and screening it for disease before the embryo is implanted. Until now, PGD has largely relied on searching for specific mutations,
