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…)

Illumina Asserts Its Claim of a $1,000 Whole Human Genome, But Is Gene Sequencing Ready for Use by Clinical Pathology Laboratories?

This price includes all costs except overhead, but without a high volume of customers, Illumina’s $10-million price for the HiSeq X Ten machine may not be a wise investment

Competition continues to be fierce in the race to the $1,000 whole human genome. Most recently, Illumina announced the availability of its latest gene sequencing system, along with the claim that it can deliver a whole human genome at a cost of just $1,000. But, as most pathologists know, the devil is in the details, since not every Illumina customer is likely to achieve that price point.

When Illumina, a San Diego-based technology company, announced its new HiSeq X Ten genetic-sequencing machine in December, 2013, Illumina CEO Jay T. Flatley claimed the company’s system can deliver “full-coverage human genome sequences for less than $1,000,” down from $500 million 10 years ago. The new system is expected to ship in the first quarter of 2014.
