Plural Molecular and Cellular Mechanisms of Pore Domain KCNQ2 Encephalopathy
Abreo et al., eLife. 2025.
https://pmc.ncbi.nlm.nih.gov/articles/PMC11703504
This study investigates the cellular and molecular mechanisms underlying KCNQ2 encephalopathy, a severe type of early-onset epilepsy caused by mutations in the KCNQ2 gene. Researchers describe a case study of a child with a specific KCNQ2 gene mutation, G256W, and found that it disrupts normal brain activity, leading to seizures and developmental impairments. Male and female Kcnq2G256W/+ mice have reduced KCNQ2 protein levels, epilepsy, brain hyperactivity, and premature deaths. As seen in the patient study, ezogabine treatment rescued seizures in mice, suggesting a potential treatment avenue. These findings provide important insights into KCNQ2-related epilepsy and highlight possible therapeutic strategies.

Commentary: The International Mouse Phenotyping Consortium: High-Throughput In Vivo Functional Annotation of the Mammalian Genome
Lloyd, Mammalian Genome. 2024.

The International Mouse Phenotyping Consortium (IMPC), a collectively governed consortium of 21 academic research institutions across 15 countries on 5 continents, represents a groundbreaking approach in genetics and biomedical research. Its goal is to create a comprehensive catalog of mammalian gene function that is freely available and equally accessible to the global research community. So far, the IMPC has uncovered the function of thousands of genes about which little was previously known. By 2027, when the current round of funding expires, the IMPC will have produced and phenotyped nearly 12,000 knockout mouse lines representing approximately 60% of the human orthologous genome in mice. This new knowledge has produced numerous insights about the role of genes in health and disease, including informing the genetic basis of rare diseases and positing gene product influences on common diseases. However, as IMPC nears the end of the current funding cycle, its path forward remains unclear. Supported by ORIP (UM1OD023221).
