Yaping Yang, laboratory director of the Whole Genome Laboratory at Baylor, and Christine Eng, professor of molecular and human genetics at Baylor and senior director of Baylor's Medical Genetics Laboratories, found a molecular diagnosis (meaning a genetic mutation or variation linked to a disease) in 25 percent of the large group of cases confirming in this much larger group of patients the diagnostic yield from their initial report on the first 250 cases that appeared in the New England Journal of Medicine a little more than a year ago. <\/p>\n Eng will also present results of the study on Oct. 21 during the American Society of Human Genetics Annual Meeting in San Diego, Calif. <\/p>\n \"The findings in this report, I believe, will forever change the future practice of pediatrics and medicine as a whole,\" said Dr. James R. Lupski, professor of molecular and human genetics and pediatrics at Baylor and a coauthor of the report. \"It is just a matter of time before genomics moves up on the physician's list of things to do and is ordered before formulating a differential diagnosis. It will be the new 'family history' that, better yet, gets you both the important variants inherited from each parent and the new mutations that contribute to disease susceptibility.\" <\/p>\n In fact, a large percentage of the diagnoses made were patients who inherited a new mutation (in the egg or sperm) that was not previously seen in their parents. <\/p>\n \"The routine application of new genome methods in the clinic is not only benefitting patients but changing the way we think about research,\" said Dr. Richard Gibbs, director of the Baylor College of Medicine Human Genome Sequencing Center and an author of the report. <\/p>\n \"It has been wonderful to watch this very large team of colleagues bridging from the patient in clinic to the very most cutting edge genomic technology to give families answers where previously there were none,\" said Dr. Arthur Beaudet, professor of molecular and human genetics who was chair of the department when the Whole Gene Laboratory was begun and who began the Baylor College of Medicine Medical Genetics Laboratories. <\/p>\n <\/p>\n Go here to read the rest: <\/p>\n Whole exome sequencing closer to becoming 'new family history'<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" PUBLIC RELEASE DATE: 18-Oct-2014 Contact: Glenna Picton picton@bcm.edu<\/a> 713-798-4710 Baylor College of Medicine @bcmhouston HOUSTON -- (Oct.
