  • Subjects: 2584 trios
  • Normal Controls: -
  • Methods: Illumina 1M/1Mduo Genechip
  • Evidence Details: Our results demonstrate that regions of HH are significantly enriched for previously reported ASD candidate genes and the observed association is independent of gene size (odds ratio 2.51).
