Genetics

Genetics is the study of genes and heredity. Heredity is the passing of genetic information and traits (such as eye color and an increased chance of getting a certain disease) from parents to offspring.

How Do Genetic Mutations Cause Disease?

Mutations in genes can lead to genetic disorders, impacting health. Understand the types, causes, and implications of genetic mutations and disease.

Children who ate healthier plant foods had slightly lower blood pressure later

Researchers followed 3,990 Dutch children for an average of 1.6 years and found that higher healthful plant-based diet scores were associated with modestly lower blood pressure and total cholesterol. Children with higher unhealthful plant-based diet scores had lower estimated food costs and distinct metabolite profiles, while healthful scores showed no clear cost association.

Largest neuroimaging study of bulimia nervosa finds structural brain differences linked to diagnosis and binge-eating severity

Researchers at the Icahn School of Medicine at Mount Sinai found that individuals with bulimia nervosa have structural differences in brain regions involved in reward and motivation, as well as social and sensory processing, and that more frequent binge eating is associated with more widespread differences in brain structure, according to research published today in JAMA Psychiatry.

New study defines rare TCF7L2-related neurodevelopmental disorder

Researchers have completed the largest study to date of TCF7L2-related neurodevelopmental disorder (TRND), a rare genetic condition caused by changes in the TCF7L2 gene, which plays an important role in brain development.

Sex-specific biological clocks reveal how aging differs across the body in women and men

Researchers developed 38 sex-specific biological aging clocks across 15 organ systems, finding differences between females and males in genetic architecture, molecular signatures, disease associations, and mortality patterns. Brain aging clocks were linked to progression from mild cognitive impairment to Alzheimer’s disease in both sexes and to sex-dependent cognitive trajectories among solanezumab-treated A4 participants, while the authors stressed that sex-pooled and sex-interaction models remain complementary approaches.

CGM reveals glucose patterns linked to cardiometabolic risk in adults without diabetes

Fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) are the clinical gold standards for screening for blood sugar levels yet they provide only static snapshots that fail to reflect the highly dynamic and heterogeneous nature of metabolic impairment.

Study identifies powerful inherited risk factor for lung cancer

A rare inherited mutation in the Epidermal Growth Factor Receptor (EGFR) gene is associated with a 25-fold increased risk of lung cancer, according to a study by investigators at Dana-Farber Cancer Institute and 23andMe Research Institute.

Scalable machine learning model maps complex genomic enhancers across tissues

Understanding gene regulation may be the key to interpreting human disease genetics. Genes are regulated in part by stretches of DNA called enhancers, which define when, where, and how strongly each gene is turned on.

What children eat may leave a measurable signature in their blood

Researchers analyzed 236 blood metabolites in 421 children to examine metabolic signatures associated with three dietary patterns characterized by core foods, animal protein sources, or poor-quality fats and sugars. The results identified distinct, biologically plausible metabolite patterns across dietary exposures, although most individual associations did not survive multiple-testing correction and require validation in independent cohorts.
