Unusual Genes Versus Osteoporosis
Learning from rare human genetics is a frequent theme in modern biotechnology and medicine; here, The Scientist looks at what might come from one rare condition: "His bone density was eight times higher than average for a man his age ... He's had several failed hip replacements because they can't screw the prosthesis into his bone. It's too hard. ... As it turned out, [osteoporosis researchers] had already zeroed in on exactly the same mutation while studying a Nebraska family with unusually dense bones. They'd identified 21 family members with the condition. ... None of those people, ranging in age from 3 to 93, had ever had a broken bone ... Many questions [remain] unanswered, but [scientists] are hopeful that clinical trials of osteoporosis treatments stemming from their work could begin within five years." As is often the case, there is a potential enhancement here - who wouldn't want stronger bones as a preventative measure?
