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.

Genetic and Cellular Architecture of Breast Cancer Risk Across Ancestries

This largest multi-ancestry breast cancer study reveals that the disease shares a largely common polygenic architecture and convergent cellular signatures across diverse ancestral groups, despite variations in specific genetic correlations and effect sizes.

Electron microscopy visualization of cell-free mitochondrial DNA-containing extracellular vesicles in human plasma, serum, and saliva

Using electron microscopy to analyze human biofluids, this study demonstrates that cell-free mitochondrial DNA is often associated with double-membrane, mitochondria-like particles rather than existing as naked DNA, suggesting a potential role in intercellular mitochondrial transfer or signaling.

Cross-ancestry evaluation of idiopathic pulmonary fibrosis genetic risk variants

This study evaluates the transferability of 35 known idiopathic pulmonary fibrosis genetic risk variants in non-European populations, finding that while most show limited cross-ancestry consistency, the MUC5B variant remains a dominant signal, underscoring the need for larger, diverse studies to improve genetic discovery and translation.

From GWAS to drug: A framework for drug candidate prioritisation using a gene expression signature matching approach

This paper systematically benchmarks key parameters of the transcriptome-wide association study (TWAS) signature-matching approach using three proof-of-concept traits and proposes a best-practice framework to optimize the prioritization of drug candidates supported by human genetic evidence.

Meta-Analysis of Rare Cancers Leveraging Clinically Ascertained Cohorts Reveals Novel Germline Susceptibility Loci

By integrating large-scale clinically ascertained cohorts with population biobanks, this meta-analysis of over 480,000 individuals identified nine novel germline susceptibility loci across eight rare cancer types, revealing critical insights into host-viral interactions, somatic-germline interplay, and hematopoietic dysregulation that advance the understanding of inherited susceptibility in rare malignancies.

Biventricular cardiac dynamic shape: genetics and cardiometabolic disease associations

This study demonstrates that a novel dynamic cardiac shape atlas derived from UK Biobank CMR imaging captures unique functional remodeling patterns and genetic loci not reflected in standard measures, thereby significantly improving the prediction of incident cardiometabolic diseases and offering new insights into the genetic architecture of cardiac function.

PALM3 and hearing loss: a potential dual diagnosis interfering with novel gene discovery

This study identifies a homozygous splice-site variant in PALM3 as a likely cause of autosomal recessive non-syndromic hearing loss in a consanguineous family, supported by functional evidence of loss of function and mouse model data, while highlighting the challenge of distinguishing this novel gene from a concurrent OTOA variant in dual molecular diagnoses.

Polygenic risk scores enhance the identification of carriers of monogenic forms of idiopathic pulmonary fibrosis

This study demonstrates that incorporating polygenic risk scores (PRS) for idiopathic pulmonary fibrosis into clinical models significantly improves the identification of patients carrying rare deleterious variants, thereby offering a valuable criterion for prioritizing individuals for genetic testing.

Genetic analysis of female genital tract polyps implicates genome stability, estrogen signalling and shared susceptibility with proliferative gynaecological disorders

This genome-wide association study of over 48,000 cases identifies 52 risk loci for female genital tract polyps, revealing that their development is driven by a systemic interplay of compromised genome stability and dysregulated estrogen signaling, which shares significant genetic susceptibility with other proliferative gynecological disorders like endometriosis, fibroids, and endometrial cancer.
