Genetic and genomic medicine explores how our DNA shapes health, disease risk, and responses to treatment. This rapidly evolving field moves beyond simple family trees to examine the complex molecular instructions that guide every cell in the human body. By decoding these biological blueprints, researchers aim to unlock personalized therapies that target the root causes of illness rather than just treating symptoms.

On Gist.Science, we bring the latest discoveries directly from medRxiv, the leading preprint server for health sciences. We process every new submission in this category as it arrives, transforming dense academic findings into both detailed technical breakdowns and clear, plain-language summaries. This ensures that groundbreaking research is accessible to clinicians, scientists, and curious readers alike without the usual barriers of jargon.

Advancing precision medicine in the Cardiac Intensive Care Unit using universal whole-genome sequencing

A retrospective review of Primary Children's Hospital's universal whole-genome sequencing protocol for neonates with congenital heart defects revealed that 19.4% of patients had clinically relevant genetic findings, with 10.6% receiving a causative diagnosis that often occurred before the emergence of extracardiac features, thereby enabling timely medical management and informed family decision-making.

Huntingtin CAG repeat is a continuous modifier of brain structure and health vulnerability

This study demonstrates that the Huntingtin CAG repeat length acts as a continuous quantitative modifier of brain structure and neuropsychiatric vulnerability across the general population, challenging the traditional view of it as a purely categorical determinant of Huntington's disease.

Genetic regulation of cell type-specific chromatin accessibility shapes immune function and disease risk

This study presents a comprehensive single-cell map of chromatin accessibility across 3.5 million human immune cells from over 1,000 donors, revealing that integrating cell type-specific caQTLs with multi-omics data significantly enhances the identification of disease-associated regulatory mechanisms and gene networks compared to traditional approaches.
