Researchers at Columbia University Report How Exome Sequencing Helped Diagnose Patients with Unknown Disorders
More precise diagnoses will encourage pathologists and clinical laboratory professionals to consider using exome sequencing for clinical diagnostic purposes
Having sequenced the exomes of 150 patients to diagnose unknown disorders over the past year, physicians at Columbia University (CU) used that information to make decisive diagnoses in one-third of the cases. It is evidence from one of the nation’s pioneering gene-sequencing programs that such data can improve how physicians identify disease.
Findings from Exome Sequencing Program Noteworthy for Pathologists
Pathologists will find it noteworthy that some of the patients in the exome-sequencing program had been tracked for years at CU without a definitive diagnosis. This is why clinicians at the academic center in New York City see value in exome sequencing for selected patients.
For more than a year, doctors at Columbia University have tested the exome’s capability to provide a correct diagnosis for patients with suspected genetic disorders of unknown origins. The primary goal of the program is to prove that sequencing the exomes of these patients is both clinically useful and cost effective in guiding physicians to a correct diagnosis. (more…)
