The U.K. has released a huge repository of children’s genomic data after sequencing blood samples from three large cohorts recruited at birth and followed across three decades. The power of the data is amplified by the large volume of longitudinal health information, biological samples and responses to surveys and questionnaires that has been provided by participating families. Before this, large-scale publicly available genome sequences were limited to adult cohorts, and the only childhood genome sequence data was from children with rare diseases.
Neurenati Therapeutics Inc.’s NEU-001 has been awarded U.S. orphan drug and rare pediatric disease designations by the FDA for the treatment of Hirschsprung disease.
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.
Too much of a good thing, it turns out, is a concept that applies to oxygen. And researchers at the University of California at San Francisco are working on a small molecule, Hypoxystat, that can lower tissue oxygen levels and prevent damage when oxygen levels are too high. When administered to mice with the rare mitochondrial disorder Leigh syndrome, the molecule more than tripled their average lifespan.
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.
The most common form of hereditary deafness in humans is caused by mutations in the GJB2 gene, which encodes the gap junction protein connexin 26. That regulates the transport of potassium and metabolites between inner ear cells. The coding sequence of this gene fits in an adenovirus-associated vector (AAV), making it an attractive approach for gene therapy.
Researchers have altered the genetic code in a strain of Escherichia coli, reducing the number of stop codons from three to one and assigning the freed-up stop codons to nonstandard amino acids. They reported on the recoded bacterium, which they named OCHRE, in Nature on Feb. 5, 2025.
A new version of Evo, the AI developed at the Arc Institute that can be used to design genomes as long as that of a bacterium, has been retrained with the DNA sequences of three domains of life – viruses, bacteria and eukaryotes.
Ensoma Inc.’s lead program, EN-374, has been granted orphan drug and rare pediatric disease designations by the FDA for the treatment of X-linked chronic granulomatous disease. Ensoma anticipates filing an IND application for EN-374 in the first half of this year.
Researchers at E-Therapeutics plc recently presented efficacy and safety data on ETX-148, a pan-hemophilia agent in murine models of hemophilia A and B.
