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.

Genomics and AI identify a candidate gene behind rare neurodevelopmental disorder

Researchers at Baylor College of Medicine, the Duncan Neurological Research Institute (Duncan NRI) at Texas Children's Hospital, the Texome Project and collaborating institutions have identified variants in gene BRSK1 as a likely diagnosis for individuals with a rare and complex neurodevelopmental disorder who until now had not received an explanation for their condition.

Zebrafish study reveals how albinism gene influences embryonic eye development

Tiny, striped zebrafish are helping scientists trace how a gene linked to albinism influences eye development, work that may ultimately help explain some of the vision problems experienced by people with the condition and guide the search for new treatments.

EGFR co-targeting and nanotechnology offer new triple-negative breast cancer therapies

Triple-negative breast cancer (TNBC) remains one of the most challenging forms of breast cancer to treat because it lacks the estrogen, progesterone and HER2 receptors that enable targeted treatment in other breast cancer subtypes.

A child's gut microbiome may offer early clues to type 1 diabetes risk

Researchers tracking 887 children at high genetic risk of type 1 diabetes identified three distinct patterns of gut microbiome maturation during early childhood. One pattern was associated with substantially higher risk of islet autoantibody seroconversion or type 1 diabetes, while host genetic background altered the risk associated with another pattern.

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.
