Admittedly, I am a bit behind in my journals, so I only recently read articles in Nature entitled Secrets of the Human Genome Disclosed and Genomes on Prescription. The first article was about geneticist Ghoulson Lyon, who presented a research study at a conference on a family suffering from an unknown, apparently genetic, disease. He was trying to find genetic variants associated with the disease, which caused some male children in the family to die before they reached their first birthday.
