Scientists at Princeton and the Simons Foundation have identified four biologically distinct subtypes of autism, using data from over 5,000 children and a powerful new computational method. These ...

For many years, autism has been identified as a spectrum with differing levels of ability. New research suggests that the age when symptoms first appear may help anticipate the specific traits, ...

In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. “Epigenetic” marks — chemical modifications to DNA that don’t change the DNA ...

Genetic information in the DNA and modifications, such as DNA methylation, define the epigenetic landscape and phenotype and show both Mendelian and non-Mendelian heredity. Scientists have long known ...
