Unique genetic basis found in autism genes that may lead to earlier diagnosis

(American Associates, Ben-Gurion University of the Negev) One particularly distinct characteristic of autism genes the researchers found is their exceptional genomic length, which is longer than other brain-expressed genes of closely related diseases such as Alzheimer's and schizophrenia. Additionally, when the researchers studied families that have a child diagnosed with ASD, they found a unique genomic signature shaped by negative selection, an evolutionary process that purifies and removes disruptive mutations from genes and prevents them from replicating over generations.
