PROBLEM TO BE SOLVED: To provide a technology for selecting a specific SNP (single nucleotide polymorphism) having significant association with an attack of attention deficit hyperactivity disorder and using the SNP as a marker to predict the attack risk of attention deficit hyperactivity disorder.SOLUTION: A method is provided for predicting the attack risk of attention deficit hyperactivity disorder by confirming the nucleotide of rs550818 SNP in a GIT1 gene, which is polynucleotide including C or T at the 24926101st nucleotide on human chromosome 17. Further, a composition is provided for diagnosing the attack risk of attention deficit hyperactivity disorder, including a probe for detecting the SNP or a primer for amplifying a chromosomal region, and a diagnosing kit with the probe fixed onto the surface is provided. The prediction method, the diagnostic composition and the kit are therefore useful technologies that can conveniently classify attack risk groups for attention deficit hyperactivity disorder with high sensitivity to permit prevention or early detection of these risk groups.
