Case-control analysis revealed lack of any significant difference in allelic frequencies between ADHD probands, their parents and controls P>0.05. rs3746544 'T' allele also showed mild over transmission from parents to probands, with a power of 67.6%, primarily due to a bias in maternal transmission. Comparative analysis of all published reports on rs3746544 also revealed statistically significant transmission of rs3746544 'T' allele. More... Non-significant

A significant difference was determined between the groups f...... A significant difference was determined between the groups for SNAP-25 (rs3746544). SNAP-25 (rs3746544) exhibited a significant difference between the ADHD and HC groups. T allele frequency was higher in parents with children with ADHD compared with the HC group, while G allele frequency was higher in the HC group. There were no differences in allele frequencies for SNAP-25 (rs3746544) between the ADHD and Non-ADHD groups, or the Non- ADHD and HC groups , after the Bonferroni correction. For SNAP-25 (rs3746544), while the G allele presence exhibited no significant difference among the groups, the presence of the T allele in the ADHD and non-ADHD groups was higher than that in the HC group. In contrast, there was no significant difference in terms of the presence of the G or T alleles between the ADHD and the Non-ADHD groups. More... Significant
