The human genome has yielded another round of secrets with the publication of two back-to-back papers in Nature on July 23, 2025. Both studies re-sequenced probands from the open-access 1000 Genomes Project, which was one of the first projects to sequence individuals from diverse populations. While one paper “goes very deep and tries to reconstruct a few genomes to basically near completion,” the other specifically looked at structural variants in a larger number of genomes. Together, they give new insights into genome variation.
Researchers have identified bi-allelic variants in the POPDC2 gene as the cause of a rare inherited cardiac syndrome characterized by sinus node dysfunction, atrioventricular (AV) conduction defects and hypertrophic cardiomyopathy.
Fragile X syndrome (FXS), the most common inherited cause of intellectual disability and autism, is caused by silencing of the Fmr1 gene, leading to a lack of the FMRP protein, which regulates protein synthesis in neurons. One key pathway affected by FMRP loss is the metabotropic glutamate receptor 5 (mGluR5) signaling pathway, where activation of mGluR5 leads to excessive translation of several proteins involved in synaptic plasticity.
The Cystic Fibrosis Foundation has agreed to provide Prime Medicine Inc. an additional investment of up to $24 million to continue the development of a gene editing therapy for people with cystic fibrosis. Prime Medicine uses a gene editing technology called prime editing, which enables a wide range of modifications to the DNA with a high degree of precision.
The U.S. FDA has cleared Aavantgarde Bio Srl’s IND application for AAVB-039, the company’s gene therapy program for Stargardt disease, the most common inherited form of macular degeneration.
FAST kinase domain-containing protein 5 (FASTKD5) is a mitochondrial protein that is needed for processing mRNA in the primary mitochondrial transcript. Several mutations have been found in other proteins involved in mitochondrial metabolism, but mutations in the FASTKD5 gene have not yet been reported.
Lizards, zebrafish, salamanders and tritons can regrow a tail, a fin, or even an entire limb after amputation. Cut a planarian into pieces, and you will end up with a bunch of them. Researchers at the National Institute of Biological Sciences in Beijing have discovered a genetic switch linked to vitamin A. After activating this pathway, they managed to regenerate the ear pinna of a mouse, an animal that previously lacked this ability.
Hutchinson-Gilford progeria syndrome (HGPS), an extremely rare genetic disorder, arises when a silent point mutation in the gene encoding the nuclear envelope protein lamin A, LMNA, leads to abnormal splicing of LMNA mRNA.
Cellular atlases and omics studies, such as genomics, transcriptomics and proteomics, have become key tools for identifying the diversity of all the elements that make up the cardiovascular system. These approaches help scientists understand how cells, genes and molecules function and interact in both healthy and diseased conditions, revealing critical points where targeted interventions could not only relieve symptoms but potentially reverse the underlying pathology at its origin.
