Single nucleotide polymorphisms (SNPs) are the most common types of genetic variation among people.
Tags on DNA from fathers' sperm may be linked to children's autism symptoms.
With three billion letters in the human genome, it seems hard to imagine that simple gene insertions and deletions could have much of an impact.
Long thought to be more limited, research says that small differences in as many as 1000 genes add to autism risk, according to a new study. Here's how.
Most of the genetic risk for autism comes from versions of genes that are common in the population, rather than from rare variants or spontaneous glitches.
A large twin study found that shared environment influences susceptibility to autism more than expected. Find out the role of experiences and exposures.
Hundreds of small genetic variations are associated with autism, including an area of DNA that may be key to understanding why humans are social animals.
Insights from epigenomic maps will help determine the role the epigenome plays in learning, memory formation, brain structure and mental illness.
Many diseases have origins in the genome or in reversible chemical changes to DNA - the epigenome. Now, a new tool pinpoints genetic sources of disease.
Three new autism gene networks discovered, and research points to brain’s glutamate signaling related to autism, ADHD and schizophrenia.
Genetic variants associated with vitamin B12 have been researched and revealed. Find out more here!
Scientists have developed a tool to help researchers & clinicians identify disease-causing genetic variations in families faster & more precisely than ever.
Schizophrenia is one of the most prevalent, tragic, and frustrating of all human illnesses, affecting about 1% of the human population.
Decoding the complete DNA genome in a single cell has been a major goal of technology developers. But the methods aren't quite able to deal with that yet.
Researchers are trying to understand the reasons why some people grow out of their childhood attention-deficit/hyperactivity disorder (ADHD) and some don't.
New tests that scan all of a person's genes -- that person's "genome" -- or large parts of his or her genome are now on the market.
The choreography of human brain development is amazing, but quite mysterious.
A personalized vitamin & mineral supplement plan may be in your (near) future
No doubt your family tree gets fuzzy the further back you go.
Deoxyribonucleic acid (DNA) is the chemical compound that contains the instructions needed to develop and direct the activities of nearly all living organisms. DNA molecules are made of two twisting, paired strands, often referred to as a double helix.
The three billion letters of the human genome are written using the four-letter alphabet of DNA. The DNA is divided among 23 pairs of chromosomes that are found in each of the trillions of cells in our bodies.
A study published in Nature shed light on how the extra chromosome 21 upsets the equilibrium of the entire genome, causing a wide variety of pathologies.
