On December 18, 2007, the United Nations General Assembly adopted resolution 62/139, tabled by the State of Qatar, which declares April 2 as World Autism Awareness Day (WAAD) in perpetuity. Her Highness Sheikha Mozah Bint Nasser Al-Missned, Consort of His Highness Sheikh Hamad Bin Khalifa Al-Thani, the Emir of the State of Qatar, supported the campaign for a World Autism Awareness Day through the current 62nd UN General Assembly Session, garnering consensus support from all United Nations Member States.

This UN resolution is one of only three official disease-specific United Nations Days and will bring the world’s attention to autism, a pervasive disorder that affects tens of millions. The World Autism Awareness Day resolution encourages all Member States to take measures to raise awareness about autism throughout society and to encourage early diagnosis and early intervention. It further expresses deep concern at the prevalence and high rate of autism in children in all regions of the world and the consequent developmental challenges.

World Autism Awareness Day shines a bright light on autism as a growing global health crisis. WAAD activities help to increase and develop world knowledge of the autism epidemic and impart information regarding the importance of early diagnosis and early intervention. Additionally, WAAD celebrates the unique talents and skills of persons with autism and is a day when individuals with autism are warmly welcomed and embraced in community events around the globe.

By bringing together autism organizations all around the world, we will give a voice to the millions of individuals worldwide who are undiagnosed, misunderstood and looking for help. Please join us in our effort to inspire compassion, inclusion and hope.

Study finds chromosomal microarray analysis detects more abnormalities

By Jenifer Goodwin | HealthDay Reporter

A newer type of genetic test is better at detecting abnormalities that predispose a child to autism than standard genetic tests, new research has determined.

Researchers offered about 933 people aged 13 months to 22 years who had been diagnosed with an autism spectrum disorder three genetic tests: G-banded karyotype testing, fragile X testing or chromosomal microarray analysis (CMA), which has been available only for the past few years.

Karyotype tests identified chromosomal aberrations associated with autism in about 2 percent of patients, while the fragile X genetic mutation was found in about 0.5 percent of patients.

CMA detected chromosomal abnormalities in slightly more than 7 percent of patients, making it the best available genetic test for autism spectrum disorders, the study authors said.

“The CMA test alone has triple the detection rate of karyotyping or fragile X,” said co-senior author Bai-Lin Wu, director of the Genetics Diagnostic Laboratory at Children’s Hospital Boston. “CMA should be added to first-tier genetic testing for autism spectrum disorders.”

The study appeared online March 15 and will be published in the April print issue of Pediatrics.

“When parents have a child diagnosed with an autism spectrum disorder, one of the first questions they often ask is ‘how did this happen?’ ” said Dr. Robert Marion, a pediatric geneticist at Children’s Hospital at Montefiore Medical Center in New York City.

“In the vast majority of cases, we believe there is at least a genetic predisposition to autism, but the ability to identify a specific genetic cause has been very elusive,” Marion said. “Part of that is because of the technology that’s been available. A larger part is at this point, we just don’t fully understand what the genetic mechanism that leads to autism is.”

Standard practice is to offer children with autism two tests as a first-line genetic work-up: karyotype and fragile X testing, the researchers said.

In karyotyping, forms of which have been around since the 1960s, geneticists use a microscope to look for chromosomal abnormalities that are associated with autism, explained Dr. David Miller, a clinical geneticist and assistant director of the Genetics Diagnostic Laboratory at Children’s Hospital Boston, which conducted the new research along with Boston’s Autism Consortium.

Like karyotyping, CMA also looks for chromosomal abnormalities, but does so at 100 times the resolution of the earlier test, Miller said. CMA, a genome-wide test, can identify sub-microscopic deletions of duplications of DNA sequences, called copy-number variants, known to be associated with autism, he said. (more…)
