AbstractIn this study we have used high-resolution genome-wide DNA copy number screening by array-based comparative genomic hybridization (array CGH) to identify the underlying genetic cause of this malformation syndrome. Through this screening we identified overlapping microdeletions on chromosome 8 in two CHARGE patients. These microdeletions pointed us to CHD7, the gene mutated in the majority of cases. These results were published in Nature Genetics.
This study demonstrates an effective novel approach to identify disease-causing genes. This approach is of special interest for sporadic malformation syndromes that cannot be tackled by other mapping approaches because of reproductive lethality.
The immune system is a striking example of an integrated information system, engaged in coordinated host-protective activities. Organs-on-chip approach (OOC) models allow the direct simultaneous observation of hundreds of different cells, moving, interacting and responding to signals coming from the microenvironment nearby, that give access to a number of parameters describing the system that must be properly measured and elaborated.READ MORE
