Table 5 General discriminant analysis of DRD2 rs1800498 and PPP1R1B rs1495099 genotypes towards prediction of ASDs in affected males 1

From: DRD2 and PPP1R1B (DARPP-32) polymorphisms independently confer increased risk for autism spectrum disorders and additively predict affected status in male-only affected sib-pair families

  1. 1One affected individual was randomly chosen from each family
  2. 2Chi-statistic reported for additive test of DRD2 and PPP1R1B and F statistic reported for single gene tests
  3. 3P-values less than 0.05 are in bold and P-values which remain significant following false-discovery rate (FDR) corrections for multiple comparisons are underlined.
  4. 4P-value ≤ FDR threshold is significant
