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.

Below are the most recent papers in genetic and genomic medicine, organized for your review.

Incorporating phenotype heterogeneity in disease GWAS improves power while maintaining specificity

The paper introduces StratGWAS, a scalable framework that improves the power and specificity of genome-wide association studies for heterogeneous diseases by leveraging secondary clinical features to stratify cases and upweight those with higher inferred genetic liability, thereby identifying more significant genetic loci than standard methods.

Leveraging human genetic variation to therapeutically target hundreds of genes with dominant & dispensable disease alleles

This paper identifies a novel therapeutic strategy that leverages common heterozygous genetic variants to enable allele-specific, mutation-agnostic silencing of over 500 dominant and dispensable disease alleles across diverse physiological systems, thereby dramatically expanding the pool of treatable patients compared to mutation-specific approaches.

Lung adenocarcinoma WHO histological classes contain distinct immune cell profiles

This study demonstrates that lung adenocarcinoma histological subtypes defined by WHO classification exhibit distinct immune cell and transcriptomic profiles that correlate with survival and immunotherapy responsiveness, offering a more prognostically valuable framework than mutation analysis alone.

Nastase, A., Olanipekun, M., Starren, E., Willis-Owen, S. A. G., Mandal, A., Domingo-Sabugo, C., Morris-Rosendahl, D., Lim, E., Liang, L., Nicholson, A. G., Moffatt, M. F., Cookson, W. O. C.2026-03-26📄 genetic and genomic medicine

Spatio-Temporal Landscape of Whole-Genome DNA Methylation Patterns in Ovarian Cancer

This study presents a comprehensive resource of whole-genome DNA methylation patterns in 404 high-grade serous ovarian cancer samples, revealing that the regulatory methylome is established early and remains stable during chemotherapy, with widespread promoter hypermethylation in treatment-resistant ascites cells driving therapy failure and offering detectable epigenetic signatures for liquid biopsy monitoring.

Marchi, G., Lavikka, K., Li, Y., Isoviita, V.-M., Micoli, G., Afenteva, D., Pöllänen, E., Holmström, S., Häkkinen, A., Valkonen, E., Maarala, I., Astren, J., Facciotto, C., Dietlein, F., Hietanen (…)2026-03-25📄 genetic and genomic medicine

Cross-omic dissection reveals locus-specific heterogeneity and antagonistic pleiotropy between Alzheimer's disease and type 2 diabetes

This study employs an integrative cross-omic framework to demonstrate that the genetic relationship between Alzheimer's disease and type 2 diabetes is characterized not by a simple shared-risk model, but by locus-specific heterogeneity and antagonistic pleiotropy, where shared genetic signals often exert opposing effects on the two diseases.

CanVar-UK: an online data platform supporting collaborative diagnostic interpretation of germline variants in cancer susceptibility genes

CanVar-UK is a freely accessible online platform that supports the collaborative interpretation of germline variants in cancer susceptibility genes by aggregating diverse variant-level data, linking to clinical databases, and facilitating diagnostic discussions among a growing international community of users.

Rowlands, C. F., Choi, S., Allen, S., Kuzbari, Z., Cubuk, C., Sultana, R., Torr, B., Durkie, M., Burghel, G. J., Robinson, R., Callaway, A., Field, J., Frugtniet, B., Palmer-Smith, S., Grant, J., Paga (…)2026-03-25📄 genetic and genomic medicine

Integrating 730,947 exome sequences with clinical literature improves gene discovery

The paper introduces gnomAD v4, a massive database of 807,162 individuals, alongside refined loss-of-function annotation and a novel Bayesian framework integrating clinical literature to significantly enhance gene discovery and rare disease diagnosis.

Preferences and willingness-to-pay for expanded carrier screening programmes in the general population: An integrative systematic review and meta-analysis

This integrative systematic review and meta-analysis synthesizes data from 31 studies to characterize the general population's preferences for expanded carrier screening program attributes and estimates a median willingness-to-pay of $107, despite noting a high risk of bias in most included studies.

Prenatal diagnosis of sickle cell disease by amniocentesis using FTA technology in a context of precariousness in sub-Saharan Africa: Challenges and perspectives

This study demonstrates that FTA Elute technology enables reliable, rapid, and cost-effective prenatal diagnosis of sickle cell disease via amniocentesis in resource-limited settings like Kinshasa, while also characterizing the socioeconomic and genetic profiles of the couples seeking these services.
