Experts Recommend 3-Step Diagnostic Process for Autism
A new study of two different kinds of genetic tests identified ASD in a small number of patients, leading the test’s authors to recommend a 3-step diagnostic process when autism is suspected.

What is the Epigenome?
DNA modifications that do not change the DNA sequence can affect gene
activity. Chemical compounds that are added to single genes can regulate
their activity; these modifications are known as epigenetic changes.

How do Geneticists Indicate the Location of a Gene?
Geneticists use maps to describe the location of a particular geneon a chromosome. One type of map uses the cytogenetic location todescribe a gene's position.

What Did the Human Genome Project Accomplish?
In April 2003, researchers announced that the Human Genome Project
had completed a high-quality sequence of essentially the entire human
genome. This sequence closed the gaps from a working draft of the
genome, which was published in 2001.

What are the Next Steps in Genomic Research?
Discovering the sequence of the human genome was only the first step in
understanding how the instructions coded in DNA lead to a functioning
human being. The next stage of genomic research will begin to derive
meaningful knowledge from the DNA sequence.

What Were the Goals of the Human Genome Project?
The main goals of the Human Genome Project were to provide a
complete and accurate sequence of the 3 billion DNA base pairs that make
up the human genome and to find all of the estimated 20,000 to 25,000
human genes.
