Reference Statistical Values/Author Comments Result of Statistical Analysis
Sanchez-Mora C, 2010 no association between the p.Val66Met polymorphism and ADHD Non-significant
Schimmelmann BG, 2007 the result did not support for an involvement of the Val66 allele of the Val66Met polymorphism of BDNF in the pathogenesis of ADHD in this sample Non-significant
Friedel S, 2005 revealed no significant differences in genotype or allele distributions Non-significant
Cho SC, 2010(a) The T-G-G haplotype was significantly less frequent and A-G-G was more frequent in girls with ADHD than in control girls, haplotype specific T-G-G P-value=0.005, haplotype specific A-G-G P-value=0.048, haplotype global P-value=0.027; AA genotype of rs 11030101 was significantly associated with ADHD only in girls, P-value=0.024, OR=3.00 Significant
Gizer IR, 2009 The present study does not support a relation between ADHD and this gene. Non-significant
Aureli A, 2010 two investigated BDNF SNPs were siginificantly associated with ADHD Significant
Thakur G. A., 2012 SNP rs6265 mapped to this gene showed no significant association with ADHD in this study. Non-significant
Tzang RF, 2013 No significant or Trend associated SNP was mapped in this gene. Non-significant
Xu X, 2007(b) Haplotype test for Val66/270T: TDT P-value=0.032, HHRR P-value=0.012, TRANSMIT P-value=0.014 for Taiwanese samples; TDT P-value=0.016, HHRR P-value=0.013, TRANSMIT P-value=0.07 for pooled samples. Haplotype analyses found evidence for decreased transmission of the Val66/270T haplotype in the Taiwanese sample and the pooled Taiwan/UK sample. Significant
Ribases M, 2008 1 SNP showed significant association with both adulthood and childhood ADHD; 1 SNP showed significant association with childhood ADHD Significant
Lanktree M, 2008 haplotype A-G-A-G-T P-value=0.0086, X2 =6.90 in the family-based sample, P-value=0.025, X2 =5.04, OR=1.47 in the combined samples; haplotype G-A-G-C-C P-value=0.0054, X2 =7.75, OR=0.46 in the case-control sample, P-value=0.0013, X2 =10.37, OR=0.50 in the combined samples; allelic and haplotype association was found Significant
Kent L, 2005 evidence for preferential transmission of the valine (G) allele with a strong paternal effect supported the association between BDNF and ADHD Significant
Oades RD, 2008 3 SNPs showed significant association Significant
Lee J, 2007 Haplotype TRANSMIT Analysis: Global P-value=0.096 on 3 df for haplotypes with frequencies>10%; P-value=0.021 for haplotype AGG (frequency 2.2%) | quantitative analyses of haplotype: smallest P-value=0.008 for AGG in Parent rated hyperactivity/impulsivity. Uncommon haplotype, A-G-G (frequency 2.2%), demonstrated a significant association with ADHD in categorical and quantitative analyses. However, the number of transmission for this haplotype was considered too low to provide a definitive result. Significant
Brookes K, 2006 UNPHASED TDT P-value=0.165, global P-value=0.888, WHAP TDT P_sum P-value=0.534, no SNP with nominal P-value<0.05 located in this gene Non-significant
Albayrak O., 2013 No significant association was reported in this study. Non-significant
