Genomic and molecular diagnostics have seen significant advancements, particularly in the context of rare pediatric diseases and cancer. A study focusing on pediatric disorders in the UK and Ireland demonstrated that genomewide diagnostic approaches could successfully diagnose approximately 41% of probands, with a notable 76% of diagnosed trios revealing pathogenic de novo variants (ref: Wright doi.org/10.1056/NEJMoa2209046/). In the realm of lung adenocarcinoma, researchers integrated whole-exome sequencing and RNA-sequencing data from a substantial cohort to explore the evolutionary characteristics of tumor morphology, revealing a complex relationship between histological variations and disease progression (ref: Karasaki doi.org/10.1038/s41591-023-02230-w/). Furthermore, a comprehensive genomic and transcriptomic analysis of non-small cell lung cancer (NSCLC) treated with checkpoint inhibitors identified key molecular features associated with treatment response, highlighting the importance of genomic alterations such as ATM and TERT in predicting outcomes (ref: Ravi doi.org/10.1038/s41588-023-01355-5/). These studies underscore the critical role of genomic diagnostics in informing treatment strategies and understanding disease mechanisms across various cancers.
