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.

Large-scale exposome research shows how multiple factors influence disease risk

For decades, scientists have been carefully unraveling the role of genes in disease by examining how small variations in a person's genetic code can shape lifelong risk of developing common conditions such as cancer, diabetes, or heart disease.

Study identifies a common hidden genetic cause of neurodevelopmental disorder in children

Researchers identified biallelic variants in RNU2-2 as the cause of a recessive neurodevelopmental disorder marked by intellectual disability, global developmental delay, and frequent seizures. The study suggests this condition may be the most prevalent known recessive neurodevelopmental disorder currently diagnosable by sequencing, with RNA data pointing to a loss-of-expression mechanism.

Regulatory T cells may influence inflammation and behavior in autism

Two new studies from the UC Davis MIND Institute examined regulatory T cells (Tregs) and their potential role in neuroinflammation and behavioral changes associated with autism.

Do your genes dictate how your lifestyle choices impact aging?

Lifestyle-behavioral factors and socioeconomic status play an important role in shaping healthy aging, but their effects may differ depending on your DNA, according to a new international study led by Adelaide University researchers.

NIH funds AI project to advance Alzheimer’s research and treatment

The National Institutes of Health has renewed support for Artificial Intelligence for Alzheimer's Disease, or AI4AD. The new $12.6 million award to advance the project's next phase, AI4AD2, brings its total investment in AI4AD to $30.7 million.

How vitamin D in the first 1,000 days may shape lifelong health

This narrative review argues that vitamin D is clearly important for skeletal health during the first 1,000 days of life and may also shape immune, metabolic, and selected neurodevelopmental pathways during early development. However, the authors stress that human evidence for most non-skeletal outcomes remains heterogeneous, with benefits appearing most consistent in populations with baseline deficiency.

Innate immunity genes may influence earlier breast cancer onset in BRCA1 carriers

Damaging variants in genes involved in a rapid immune response (innate immunity) are significantly linked to earlier breast cancer onset in carriers of the harmful BRCA1 genetic mutation, reveal preliminary findings published online in the Journal of Medical Genetics.

Genomic study advances prioritization of variants in cancer diagnostics

Hiroshima University researchers have developed a practical framework to identify candidate pathogenic variants hidden among the large number of variants of uncertain significance (VUS) detected in comprehensive genomic profiling (CGP) of cancers.

Excessive RNA editing enzyme alters brain circuit formation in Down syndrome

A collaborative research study co-led by scientists at the Icahn School of Medicine at Mount Sinai and the Liber Institute for Brain Development has for the first time identified a biological process that may help explain how the brain develops differently in people with Down syndrome.

How gut imbalance may drive obesity, diabetes, and heart disease

A new review argues that gut dysbiosis is closely linked to metabolic dysfunction through intertwined effects on inflammation, oxidative stress, gut barrier integrity, microbial metabolites, and epigenetic regulation. It also highlights microbiome-targeted strategies such as high-fiber diets, probiotics, prebiotics, postbiotics, exercise, and fecal microbiota transplantation as promising ways to support metabolic health.

Study proposes genetic basis for autism’s strong sex bias

Autism has a significant and enduring sex bias, with roughly four boys diagnosed for every girl. For many years, experts have believed this disparity arises primarily from diagnostic inequities because much of autism research - and the screening tools that grew out of it - has historically focused on boys, effectively setting a male standard for what autism "looks like."
