Scientists have identified an unexpected source of genetic variation in human sperm that occurs earlier in sperm development ...

Epistasis arises when alleles at one locus modify the phenotypic expression of alleles at another, generating non-additive contributions to trait variation. In natural populations, genetic variance ...

Nearly 90% of the genetic variation associated with anorexia nervosa and binge eating was not explained by BMI, pointing to ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...

A sweeping genomic analysis reveals how psychiatric disorders cluster into five biological families, exposing shared pathways and pinpointing where their genetic roots diverge. Study: Mapping the ...

A team of international scientists has uncovered the genetic underpinnings of a rare, inherited autoimmune disorder, according to a study recently published in Science Translational Medicine.

Nature and nurture both determine how likely you are to develop a particular disease. Hiroshi Watanabe/DigitalVision via Getty Images Sitting in my doctor’s examination room, I was surprised when she ...

When someone is diagnosed with depression and anxiety, it rarely surprises their clinician. When someone with schizophrenia has mood symptoms, it rarely surprises their family. Comorbidity has always ...

Gene editing may hold the key to rescuing endangered species—not just by preserving them, but by restoring their lost genetic diversity using DNA from museum specimens and related species. Scientists ...
