World’s largest autism whole genome sequencing study reveals 134 autism-linked genes

Summary:

SickKids-led study sequences the entire genomes of more than 11,000 individuals, offering new insights into the genetics that underlie autism spectrum disorder.

Excerpt from the Press Release:

Researchers from The Hospital for Sick Children (SickKids) have uncovered new genes and genetic changes associated with autism spectrum disorder (ASD) in the largest autism whole genome sequencing analysis to date, providing better understanding into the ‘genomic architecture’ that underlies this disorder.

The study, published today in Cell, used whole genome sequencing (WGS) to examine the entire genomes of over 7,000 individuals with autism as well as an additional 13,000 siblings and family members. The team found 134 genes linked with ASD and discovered a range of genetic changes, most notably gene copy number variations (CNVs), likely to be associated with autism, including ASD-associated rare variants in about 14 per cent of participants with autism.

The majority of data was drawn from the Autism Speaks MSSNG database, the world’s largest autism whole genome dataset, which provides autism researchers with free, open access to thousands of sequenced genomes.
