kkleiner writes "Twenty-year-old Brooke Greenberg hasn't grown since age five. For the last 15 years, mystified doctors have been unable to explain the cause for Brooke's disorder that has kept her aging in check. At age twenty, she maintains the physical and mental appearance of a toddler. The researchers are now are painstakingly analyzing Brooke’s entire genome in search of unique mutations. Needless to say, it is a formidable undertaking. 'Cracking the code on Brooke’s condition,' [Dr. Eric Shadt] wrote, 'is the proverbial searching for a needle in a haystack, since likely there is one or a small number of letters changed in Brooke’s genome that has caused her condition.' To find the mutation Shadt and his team are using the latest genome sequencing and analysis tools. The strategy is to compare Brooke’s genome to the genomes of her parents and three normal sisters, as well as to other available sequences from the general population, and identify gene mutations that only Brooke has."
