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.

Investigating penetrance of severe combined immunodeficiency variants in an adult population cohort: implications for genomic newborn screening

This study analyzing 490,640 UK Biobank genomes found that severe combined immunodeficiency (SCID) variants exhibit high penetrance and a low prevalence of biallelic pathogenic variants, supporting the inclusion of SCID in genomic newborn screening while highlighting the need for careful reporting of hypomorphic variants.

Neuron-Specific DNA Methylation Differences in the Prefrontal Cortex in Parkinson's Disease

This study presents the first cell type-resolved map of DNA methylation in the prefrontal cortex of Parkinson's disease patients, revealing that the disease is characterized by neuronal-specific hypermethylation at seven distinct loci, including genes such as ROBO4 and PDE4B, while showing no significant methylation changes in glial cells.

Awareness of the Importance of Genetic Counseling and Its Role in Preventing Genetic Disorders in Derna District

This cross-sectional study of 278 participants in Derna District reveals that while most individuals hold positive attitudes toward genetic counseling, significant gaps in knowledge and barriers such as fear of results necessitate targeted educational initiatives to improve its utilization for preventing genetic disorders.
