Whole genome sequencing has substantially accelerated the pace of discovery of genes that cause rare diseases, but while this has brought the diagnostic odyssey of some patients to a conclusion, 50% to 80% remain undiagnosed after initial analysis.

Whole genome sequencing has substantially accelerated the pace of discovery of genes that cause rare diseases, but while this has brought the diagnostic odyssey of some patients to a conclusion, 50% to 80% remain undiagnosed after initial analysis. Researchers in the U.K. have now developed a new framework for analyzing sequence data at a cohort level. Applying this method to almost 35,000 undiagnosed rare disease patients led to the identification of 141 new disease-gene associations.

Natera Inc., a developer of cell-free DNA testing, provided an update on its product portfolio at the J.P. Morgan Healthcare Conference on Jan. 15. The company disclosed a new version of the Signatera assay that leverages the genome. Natera said the test, now available for research and clinical use, enables bespoke assay design from a whole genome sequence of a patient’s tumor.

Artificial intelligence-powered rare disease diagnostics firm 3billion Inc. debuted on the tech-heavy Kosdaq board of the Korea Exchange Nov. 14 with its IPO raising about ₩14.4 billion (US$10.25 million) via an offering of about 3.2 million shares at ₩4,500 per share, the low end of its offering price range.

For Inocras Inc., the benefits of whole genome sequencing are two-fold. First is its explicit usefulness in diagnosing and treating hard-to-treat diseases like cancer and rare diseases. The second, less apparent, benefit lies in the data generated in the process, and its applications to current and future generations of cancer patients.

Genotype assay testing can detect new variants of the COVID-19 virus six days faster than whole genome sequencing (WGS), with results returned in just three days — compared to nine for WGS — according to a study published in the Lancet Microbe.

A landmark, real-world study in the U.K. has demonstrated that combining whole genome sequencing with clinical data enabled tailored cancer treatment and improved outcomes. At one health care center, having DNA sequence data led to changes from usual standard of care in 25% of cases. “Mostly, [patients] got into clinical trials; some got medicines they wouldn’t have got. Others avoided medicines because their genetic make-up suggested that if they were exposed to the medicines, they would be at risk of harm,” said Mark Caulfield, professor of clinical pharmacology at Queen Mary University of London, who is co-author of a paper outlining the findings in Nature Medicine, Jan 11, 2024.

Illumina Inc. released Connected Insights in a beta version for the U.S., following its commercial release in other selected countries. Connected Insights, an assay-agnostic, cloud-based software designed to streamline interpretation and reporting across next-generation sequencing (NGS) types, was initially developed for somatic oncology applications, the system will shortly also support whole genome sequencing for rare diseases.
